Description
Technical field
The present invention relates to a kind of doctor and examine report critical data tamper-resistance techniques, belong to medical domain and field of information security technology.
Background technology
The fast universal high speed development that promotes the Digital Media industry of computer technology is also more and more higher to the demand of the content protecting of Digital Media or Related product.For example: the dispute over copyright that the illegal download of the digital product of transmission Network Based and use cause; Based on distorting of the important information in e-commerce initiative or data; Important educational background and the storage of archives, written material etc. and inquiry etc.As seen, on digital media products in the situation that do not affect its use and effectively protect and differentiate that the demand of (comprising copyright protection, authentication and bill anti-counterfeit etc.) is extremely urgent.
Main Digital Media salvo is digital watermarking (digital watermarking) technology at present.Digital watermark technology as the important branch in Investigation of Information Hiding Technology field, is the effective ways of realizing that multimedia copyright protection and information integrity guarantee, is also just becoming a study hotspot of message area at present.Digital watermarking is mainly used in: copyright protection; Digital finger-print; Authentication and completeness check; Access control; Information hiding.Wherein Digital Fingerprinting Technology is to point to: be distributed in the Digital Media of different user and embed different watermarks with the information of identifying user. this watermark can according to user's sequence number and relevant Information generation, therefore just can be determined according to this finger print information its source; Information Hiding Techniques refers to: digital watermarking can be used for hiding of the key message content such as the sign, note, retrieval of works, do not need so extra data storage, and be difficult for losing. in addition, digital watermark technology can also be used for covert communications, and this is widely used in national defence and intelligence department.
At present very ripe for the tamper-resistance techniques of various Digital Medias, but aspect medical biochemical investigation report, also do not implement effective tamper-resistance techniques.Stand in the person's of being verified angle, take a true and reliable doctor and examine report and important.If examine report because some reason is taken the doctor that portion was modified, may cause great impact to its life.If the detected person holds the suspicious attitude to assay, in the situation that there is no the method, can only again check, this all brings loss for detected person's spirit and property.This shows, digital tamper-resistance techniques is applied to the medical science aspect, be and necessary.
Summary of the invention
For the defective of existing doctor's inspection report without anti-tamper measure, a kind of medical biochemical investigation report tamper resistant method is proposed.The method can be used for medical biochemical analysis project.When the detected person holds the suspicious attitude to assay, can effectively help to detect the true and reliable property of doctor's inspection report, and the recovery of original critical data.
A kind of medical biochemical investigation report critical data tamper resistant method comprises the following steps:
Step 1 is obtained the raw data source C of medical biochemical investigation equipment output;
Step 2 extracts critical data S from the data source C that obtains, comprise detected person's identity information and the key component of testing result;
Step 3 couple critical data S carries out pre-service, generates S ';
Step 4 is embedded into S ' in original check data C, and the vision of guaranteeing the integrality of the data C ' that generates and watermark sentience not;
Step 5 is carried out data transformation with S, the cryptographic hash H of computational data after conversion;
Step 6 is converted to two-dimension code with H, be presented on C ', and final the printing obtains anti-tamper survey report.
Described method also comprises step (7): the critical data S to report carries out step (5) operation, and the two-dimension code that obtains is compared with the two-dimension code of report, if different, determines to report to be tampered.
Described method also comprises step (8): after report being detected and being tampered, adopt the watermark extracting algorithm, S recovers to the report critical data, thereby obtains original examining report.
Described method, the critical data in step 2 comprise the critical data that medical biochemical equipment generates, and also comprise the critical data of initial input, as detected person's name etc.;
Described method, in step 4, the embedding algorithm is determined according to the data structure in raw data source.
Described method, in step 5, data transformation is correspondent transform one by one, guarantees that the cryptographic hash that generates is unique, thus the integrality of identification data.
Patent of the present invention can be embedded in the middle of medical biochemistry detection equipment, as the part of functions of checkout equipment; Also can make autonomous device, the data output of external and checkout equipment.
The invention solves following problem:
(1). before preventing that effectively doctor's inspection is reported in arrival detected person hand, the possibility that is tampered;
(2). obviously improved authenticity and the reliability of doctor's inspection report;
(3). can effectively identify the authenticity of doctor's inspection report;
(4). in the doctor who was modified examines report, can effectively recover original critical data, the protection of maximum possible detected person's interests.

Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
The invention belongs to tamper resistant method, the critical data that is about to user's care is hidden in the middle of report, calculates simultaneously the cryptographic hash of critical data, guarantees its true and reliable property.With reference to figure 1, the present embodiment provides a kind of digital watermark technology and cryptography knowledge of utilizing information security field, detects the true and false of medical biochemical investigation report, and can recover the method for original critical data after determining to be tampered, and comprises the following steps:
(1) obtain raw data source C.Obtain detected person's original check data from medical biochemical investigation equipment output source, according to the difference of checkout equipment, adopt corresponding data structure analysis algorithm, thereby can correctly read the each several part information of Digital Detecting report;
(2) extract critical data S.According to actual needs, can control choosing of key component data by input parameter.Simultaneously can also input some self-defined informations, combine with the key component data;
(3) critical data S is carried out pre-service and obtain S '.Comprise the conversion to data, encrypt, compression, grouping etc.And according to the needs that embed algorithm, process accordingly.
(4) S ' is embedded into generated data C ' in raw data source C.Select suitable Digital Watermarking Embedded Algorithm, the data that obtain in step (3) are embedded in the raw data source.Telescopiny will guarantee the data integrity of data C ', and the vision of watermark sentience not.
