Description
Technical Field
The invention relates to the technical field of multi-connection encryption and decryption, in particular to a multi-connection encryption and decryption method and system based on gesture displacement.
Background
Gesture recognition is one subject of computer science and language technology, with the aim of recognizing human gestures through mathematical algorithms, users can control interactions with devices using simple gestures without touching them. Gesture recognition techniques are generally divided into three categories, including: two-dimensional hand shape recognition, two-dimensional gesture recognition and three-dimensional gesture recognition.
The two-dimensional hand type recognition is the simplest type of gesture recognition, and after the two-dimensional information input is obtained, the technology can recognize a plurality of static gestures, such as fist making or five-finger opening, the encryption effect is poor, and the encryption effect is easy to crack.
Two-dimensional gesture recognition is slightly more difficult than two-dimensional hand type recognition, but still does not contain depth information and stays on a two-dimensional layer. The technology can identify hand types and can also identify some simple two-dimensional gesture actions, for example, swinging a hand towards a camera, but the existing two-dimensional gesture identification cannot meet the requirement on encryption depth.
Three-dimensional gesture recognition, the input that three-dimensional gesture recognition needs is the information that contains the degree of depth, can discern various hand types, gestures and actions. Compared with the first two-dimensional gesture/hand type recognition technologies, the three-dimensional gesture recognition cannot use only a single common camera any longer, and because the single common camera cannot provide depth information, the use cost is very high.
At present, a multi-connection password device is mostly adopted in a dense security area to protect important files, such as: administrative data of a large company and financial data of the large company, which are many and relate to confidentiality and are classified. The conventional method is that a secrecy person puts confidential data into a plurality of different secrecy boxes, and for the convenience of memory, the secrecy person sets a plurality of password devices to be the same password, or sets and records a plurality of passwords by the plurality of password devices, and inquires the password by a record book when in use.
The traditional technical scheme is not related to the technical scheme of gesture recognition encryption and decryption in the application field of the multi-connected password device, and is also the traditional digital password or fingerprint password.
Therefore, the following problems exist in the multiple encryption and decryption of the conventional cryptographic apparatus:
1) the multi-connection encryption and decryption of the traditional password device is realized through a preset digital password or a fingerprint password, the gesture recognition cannot be skillfully combined, the password structure is simple and unchanged, and the password is easy to crack by illegal people;
2) when a plurality of same passwords are set in a plurality of traditional password devices, the risk of divulging the secrets of the password devices is easily caused, and larger divulging loss is formed;
3) when a plurality of traditional password devices are set with a plurality of different passwords, the time and labor consumption of setting the passwords by a user is easily caused, the time and labor consumption of decrypting the password devices is caused, and the user experience of images is serious.

Detailed Description
In the description of the present invention, it is to be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1 to 8, a multiple encryption and decryption method based on gesture displacement is provided, and is applied to a multiple encryption and decryption system, specifically referring to fig. 3, the early warning method includes the following steps:
In this step, the multi-connection encryption and decryption system is formed by sequentially wirelessly connecting a plurality of password devices, and one of the password devices is wirelessly connected with the terminal.
It will be appreciated that, referring to fig. 1, the cryptographic device 2 is wirelessly connected to the cryptographic device 1 and the cryptographic device 3; the password device 1 is in wireless connection with the password device 2 and is connected with the mobile phone end.
The decryption operation refers to the decryption operation of executing the combined password, and comprises a digital decryption operation and a gesture data decryption operation.
The first combined password comprises a first digital password and a first gesture data password.
The digital decryption operation refers to the operation of inputting preset numbers and the sequence thereof through the number keys;
the gesture data decryption operation refers to an operation of recognizing data through the acquired two-dimensional gesture after the digital decryption operation passes verification;
and if and only if the digital decryption operation and the gesture data decryption operation pass verification, the decryption operation can be successfully decrypted.
It should be noted that the two-dimensional gesture recognition verification method is selected because the two-dimensional gesture recognition method has a higher recognition complexity than the two-dimensional hand type recognition method, so that the security is improved, but the application cost is not increased relatively significantly, and the two-dimensional gesture recognition method has a relatively simple recognition complexity and a relatively high hardware cost and software cost compared with the three-dimensional gesture recognition method. Three-dimensional gesture recognition needs a plurality of cameras to gather data in a multi-azimuth manner, and the algorithm complexity is further improved, namely the three-dimensional gesture recognition has the problems of high cost and complex algorithm, and cannot be well popularized.
At step 200, an encryption operation is performed.
In this step, when the decryption operation is successful, the encryption operation is triggered;
and the encryption operation is to form a second encryption combined password different from the second encryption combined password before decryption according to the backup encryption and decryption database.
The backup encryption and decryption database comprises a digital password packet and a gesture data packet.
The digital cipher packet is composed of a plurality of groups of digital ciphers.
The gesture data packet comprises a displacement data packet and a hand waving data packet.
The displacement data packet consists of a plurality of displacement values; the displacement value is an interval value.
The hand waving data packet consists of a plurality of hand waving values; the hand swing value comprises a hand swing direction detection value and a hand swing number value.
The second encryption combined password is composed of a digital password and gesture data which are different from those before decryption.
The second encryption combination password is a random combination of any one set of digital password in the digital password packet, any one displacement value in the displacement data packet and any one hand waving value in the hand waving data packet.
It can be understood that, when the user successfully decrypts the password device, the password device discards the encrypted password before decryption, and randomly forms a new combined password through the encrypted and decrypted database backed up inside the password device, where the new combined password is also composed of a digital password and gesture data. As shown in fig. 8, the backup encryption/decryption database of the cryptographic device includes a digital cryptographic packet, a displacement data packet, and a waving data packet. The cryptographic device can form a new combined cipher by selecting one data in each of its three packets, for example: the new combination code is '221133 + palm is 20-30cm away + hand is swung left 1 time and hand is swung right 1 time'.
It should be noted that, by setting the combination of the digital cipher packet, the displacement data packet and the hand waving data packet, the decryption difficulty of the lawless person can be greatly increased, and even if the lawless person acquires the data of the three packets, the lawless person can crash when performing the verification of the displacement data and the hand waving data because the lawless person cannot verify each displacement data and hand waving data. Meanwhile, when the data is displaced or waved once, the input of the digital password needs to be executed again, which further increases the difficulty of cracking.
And step 300, sharing the encryption password.
In this step, the encryption password refers to the second encryption combination password.
The sharing of the encryption password refers to the execution of the receiving and sending of the second encryption combined password between the password devices and the transmission of the password devices and the intelligent terminal;
in the stage of executing transceiving between the cryptographic devices, the second encryption combination cipher can only be executed by 'single sending multiple sharing';
the "single sending and multiple sharing" means that the cryptographic apparatus can only send the second encrypted combined password to another cryptographic apparatus, and then the another cryptographic apparatus sends the second encrypted combined password to the next cryptographic apparatus, and so on until the second encrypted combined password is obtained by all the cryptographic apparatuses;
in the stage of executing the sending of the password device and the intelligent terminal, any password device can send the encrypted combined password to the intelligent terminal, or a fixed password device sends the second encrypted combined password to the intelligent terminal.
The second encryption combination password is used for executing decryption of any one of the cryptographic devices again.
It can be understood that in the step of executing the sharing of the encryption password, the decentralized idea of the block chain is used for reference, so that the cost of the server side is greatly saved for the multi-connection encryption and decryption system, and the security of the multi-connection encryption and decryption system is also greatly improved. For example, the following steps are carried out: as shown in fig. 6, after the user decrypts the open device at the cryptographic apparatus 1, the cryptographic apparatus 1 forms a new combined password at the moment of successful decryption, and sends the new combined password to the cryptographic apparatus 2, and the cryptographic apparatus 2 sends the new combined password to the cryptographic apparatus 3, and then to the last cryptographic apparatus N in sequence. The password device 1 sends the new combined password to the password device 2 and also sends the new combined password to the mobile phone terminal of the user. At this time, the user can unlock one password device including all the password devices 1 to N according to the new combined password received by the mobile phone terminal. When the user opens the cipher device by using the new combined cipher, another new combined cipher is generated, and the process is circulated.
It should be noted that, as shown in fig. 1, the new combined password may be sent to the mobile phone end by the password device 1, or may be sent to the mobile phone end by another password device. Or, the password device 1 or the password device 2 or another password device may be fixed and sent to the mobile phone terminal. Such as: the password device 2 is fixed and sent to the mobile phone terminal, and after the password device 2 obtains the new combined password, the obtained new combined password is sent to the password device 3 and the mobile phone terminal. At this time, the communication cost of other cryptographic devices can be saved.
Preferably, based on step 100, in order to make the method for executing the decryption operation clearer, as shown in fig. 4, the method specifically further includes the following steps:
In this step, the user inputs the digital password at the password device to obtain the digital password.
The digital cipher may be used for digital decryption operations of any of the cryptographic devices.
And step 120, judging whether the digital password is correct, and if not, returning to the step 110.
In this step, the password device determines whether the input digital password is correct;
if the digital password is wrong, the process returns to step 110 to re-acquire the digital password.
In order to facilitate the user to execute the decryption operation, a prompting module of an LED lamp or a voice unit can be arranged on the password device and used for prompting the user whether each step is correct or wrong.
It is understood that when the user inputs a wrong numeric password, the LED light of the password device is turned on to emit red light, or the voice module of the password device prompts a "wrong" voice message.
And step 130, acquiring gesture data when the digital password is correct.
In this step, after the input digital password is correct, the gesture data verification stage can be entered to obtain the gesture data.
And the gesture data verification stage comprises displacement detection and hand waving detection.
The displacement detection refers to distance detection executed by the password device for the palm.
The hand swing detection refers to the detection of the number and sequence of hand swing performed by the password device for the palm.
It can be understood that when the user inputs the correct numeric password, the LED light of the password device is turned on to be green, or the voice module of the password device prompts the "correct" voice message.
In this step, the threshold refers to a displacement interval value in the combined cipher in the current decryption state, and is also a displacement value belonging to the displacement data packet.
The distance threshold value is a displacement interval value of the palm far away from the password device.
And when the input digital password is correct, carrying out displacement detection.
It can be understood that, as shown in fig. 5, when the digital password input by the user is correct in the combined password in the current decryption state, the detection module that detects that the palm is far away from the password device needs to reach a certain displacement value in an interval, so as to enter the hand waving detection stage.
It will be appreciated that, as shown in fig. 7, for example: the distance threshold of the combined password in the current decryption state is 15-25cm, that is, the palm is required to be detected to be away from any distance value between 15cm and 25cm of the password device, if the palm of the user stops after being away from the password device by 18cm, the user reaches the distance threshold, and if the palm of the user stops after being away from the password device by 13cm or 27cm, the user does not reach the distance threshold.
It should be noted that, in the technical scheme of this section, based on that after the user inputs the numeric code, the palm of the user is still located at the password device, and the user only needs to perform displacement detection from the numeric key, and no other body movement steps are needed, so that the user experience can be effectively improved.
If the displacement detection fails to reach the departure threshold, the process returns to step 110.
It can be understood that when the displacement detection does not reach the far threshold, the LED light of the password device is turned on to emit red light, or the voice module of the password device prompts an "error" voice message.
If the displacement detection reaches the departure threshold, step 150 is entered.
It is understood that when the displacement detection reaches a far threshold, the LED of the password device is turned on to be green, or the voice module of the password device prompts a "correct" voice message.
Step 150, when the displacement detection reaches the far threshold, determining whether the hand waving detection reaches the hand waving threshold, if not, returning to step 110.
In this step, when the displacement detection reaches the distance threshold, the hand waving detection is performed.
The hand waving threshold value comprises a hand waving direction detection value and a hand waving number value.
The hand swing direction detection value is a detection value for detecting that the palm swings left or right based on the vertical palm state.
The hand waving number value is a hand waving value obtained by waving the hand leftwards or rightwards and returning to the vertical palm state on the basis of the vertical palm state, and is used for detecting the hand waving number executed by the palm.
The hand waving detection is required to be at the position far away from the threshold value, and the preset hand waving direction detection value and the hand waving number value are reached at the same time, and then the hand waving detection is determined to reach the hand waving threshold value.
It can be understood that, as shown in fig. 7, the hand waving threshold is left 1 time and right 1 time, and the user waves the hand left and then waves the hand right again far away from the threshold, which indicates that the hand waving detection meets the hand waving threshold, and enters the decryption completion stage.
If the hand swing detection fails to reach the hand swing threshold, the process returns to step 110.
It can be understood that when the hand waving detection does not reach the hand waving threshold, the LED lamp of the password device is turned on to emit red light, or the voice module of the password device prompts an "error" voice message.
If the hand waving detection reaches the hand waving threshold, proceed to step 160.
It can be understood that when the hand waving detection reaches the hand waving threshold, the LED lamp of the password device is turned on to be green, or the voice module of the password device prompts the "correct" voice message.
In step 160, if the hand waving detection reaches the hand waving threshold, the decryption is successful, and step 200 is executed, i.e., the operation of forming a new second encryption combination password is executed.
In this step, the successful decryption means that the password device completes decryption and unlocking after the digital password and the gesture data are correctly verified.
The step of forming the second encryption combined password means that after the decryption is successful, the password device forms a combined password different from that before the decryption according to the backup encryption and decryption database.
The second encryption combination password is used for decrypting any one of the cryptographic devices again.
Example 2
A multi-connection encryption and decryption system based on gesture displacement is shown in figure 1 and comprises an intelligent terminal and a password device group.
And the intelligent terminal is used for acquiring a new combined password of one password device in the password device group.
The password device group consists of a plurality of password devices which are sequentially and wirelessly connected and used for being executed with decryption operation and encryption operation.
And after the decryption operation is finished, automatically executing the encryption operation to form a new combined password.
