In present computer utility, comprise much very secret file protection, mostly use the method for " user ID+password " to carry out user's authentication and access control.But, if once password forget, or stolen by others, the safety problem of computer system and file has just been subject to threat.Along with scientific and technological progress, user profile recognition technology has started slowly to enter in PC World.User's sign information includes but not limited to: fingerprint; Palmmprint; Impression of the hand; Dactylus prints; Vascular pattern; Retinal patterns; Iris pattern; Duct pattern; DNA sequence dna.The user profile recognition system of intelligent terminal is obtained user's sign information by sensor, by judging whether credit determines whether to allow user to login use intelligent terminal to user profile.
In user profile identification, the most typical with fingerprint recognition, refer to differentiate by the details of more different fingerprints.Because everyone fingerprint is different, be exactly that between same people's ten fingers, fingerprint also has obvious difference, so fingerprint can be used for identity authentication.Fingerprint identification technology is the most ripe and low-cost biometrics identification technology at present.The technology of fingerprint recognition application is at present very extensive, and a lot of intelligent terminals (as notebook computer, mobile phone) are the technology of employing fingerprint identification all.For convenient, below all with fingerprint recognition, the present invention will be described.
Foregoing, on intelligent terminal, use fingerprint identification technology very general, on this basis, the embodiment of the present invention proposes, after utilizing start shooting/releasing process of fingerprint, be equivalent to now intelligent terminal and known it is which credit user is in current use, now, if user wants to add digital rights information in digital document, just can directly call (finger print information is corresponding) user ID of active user's setting and add in digital document as digital rights information.Namely, specificity due to fingerprint, by setting in advance the corresponding relation of fingerprint and user ID, and after start/releasing process, when user carries out file operation, call the user ID that this fingerprint is corresponding, thereby can automatically realize the function of adding digital rights information when the operand word file for credit user.
Referring to Fig. 1, the method flow diagram that adds digital rights information in digital document providing for the embodiment of the present invention.
The method is used for intelligent terminal, such as, for mobile phone, ipad, notebook computer etc., as long as intelligent terminal has user profile recognition function, can pass through simple transformation, and realize the function of the inventive method.
The method comprises the following steps:
S101: arrange credit for verifying user's sign information of the credit of intelligent terminal start or release, be each corresponding user ID of preserving this user of user's sign information of credit;
Wherein, " release " (unlock), refers to screen or the communication lock of removing mobile communication equipment.
S102: start shooting or remove in screen locking process at intelligent terminal, obtain for verifying start or user's sign information of release, and will be verified this start or remove user's sign information that screen locking used or the user ID corresponding with this user's sign information carried out record;

S104: when user during service data file, transfers and is verified this start or removes the corresponding user ID of user's sign information that screen locking is used on intelligent terminal, user ID is added in data file as digital rights information.
The present invention, on the original fingerprint identification function of intelligent terminal basis, by calling the user ID that fingerprint is corresponding, thereby realizes the function that automatic interpolation user ID realizes copyright information for user.The present invention has utilized the fingerprint that in fingerprint recognition process, intelligent terminal obtains cleverly, by setting in advance the corresponding relation of fingerprint and user ID, when carrying out digital document operation, user ID is called, can be realized the object that automatic powder adding adds digital rights information.The present invention changes little to the existing intelligent terminal with fingerprint identification function, but can be embodied as the function that user provides digital copyright management.
Those skilled in the art can understand, and the user that the present invention mentions is credit user for intelligent terminal, are the validated users of approving by fingerprint recognition system in advance.An intelligent terminal, its credit user can be a plurality of.On method basis described in Fig. 1, if also have another credit user, be called the second user herein, pass through the inventive method, when second user's service data file, intelligent terminal can add user ID corresponding to this second user in file to as digital rights information automatically.Visible, the present invention can be implemented as different user and realizes different digital copyright information.
In the present invention, data file refers to multimedia data file, Email, internet message file, short message or multimedia message files or text.So-called multimedia data file comprises: image, sound, video file, files in stream media etc.So-called internet message file refers to the file by Internet Transmission, for example, be published to the message of microblogging, micro-letter.Text refers to the traditional data file except multimedia data file etc., includes but not limited to office office document, pdf file, database file.Office file wherein comprises again Word, Excel, Access, Powerpoint, FrontPage etc.
In the present invention, user ID includes, but are not limited to: user's signing messages, image information, and/or, user's sign information.The present invention also provides newly-built, the function revising and delete of user ID.For example, new user, utilize first fingerprint to sign in to after intelligent terminal, intelligent terminal provides the configuration block of user ID; Intelligent terminal receives the configuration parameter that new user arranges in configuration block, save as the user ID that this new user fingerprints is corresponding, thereby generate and preserve the corresponding relation of " fingerprint-user ID ", can certainly be by algorithm directly for fingerprint generates corresponding user ID.When user need to revise or delete digital rights information, user, after signing in to intelligent terminal, modifies or deletes user ID corresponding to fingerprint.Visible, the invention provides dynamic adjustment user ID and also dynamically adjust the function of digital rights information content.
Concrete, digital rights information can realize by modes such as digital watermarking, digital signature or digital certificates.
Wherein, typical digital watermarking is introduced.So-called digital watermarking is to add some numerical information to reach the functions such as the discriminating of the file true and false, copyright protection in multi-medium data (as image, sound, vision signal etc.).The watermark information embedding is hidden in host's file, does not affect ornamental and the integrality of source document.Digital watermarking process embeds some to protected digital object (as rest image, video, audio frequency etc.) exactly and can prove copyright ownership or follow the tracks of information tortious, can be sequence number, corporate logo, significant text of author etc.The concept close or in close relations with watermark has a lot, from the document of current appearance, there is concepts such as Information hiding (Information Hiding), information disguising (Steganography), digital watermarking (Digital Watermarking) and digital finger-print (Fingerprinting).Usually, digital watermarking should have following several essential characteristics: (1) vindicability: watermark should be able to provide for the ownership of information products protected by copyright complete and reliable evidence.Watermarking algorithm identification is embedded in possessory (as Subscriber Number, product marking or the significant word etc. of registration) for information about in object of protection and can in needs, be extracted.Whether watermark can be used for differentiating object and be protected, and can monitor propagation, true and false discriminating and the illegal copies control etc. of protected data.With regard to a lot of algorithms that occurred at present, assailant can destroy the watermark in image completely, or copies " original image " existing in theory, and this causes the file owner that the vaild evidence of copyright ownership can not be provided convincingly.(2) sentience not: the meaning that can not perception comprises two aspects, invisibility on a finger vision, because embed watermark causes the variation of image, to observer's vision system, should be ND, optimal situation is that watermarking images and original image are visually the same, and this is the requirement that most watermarking algorithms should reach; Watermark is also irreclaimable by statistical method on the other hand, as the information products of crossing by same method and watermark processing to a large amount of are used statistical method, also cannot extract the existence of watermark or definite watermark.(3) robustness: robustness problem is very important for watermark.Robustness is a technical term, briefly, just refer to that a digital watermarking should be able to bear a large amount of, different physics and geometric distortion, comprise (as the malicious attack) had a mind to or (as compression of images, scanning and duplicating, noise pollution, change in size etc.) unintentionally.After these operations, the watermarking algorithm of robust should still can extract the watermark of embedding or the existence of proof watermark from watermarking images.If do not grasp all relevant knowledges of watermark, the copyright protection sign of data product should be difficult to be forged.If attempting to delete watermark, assailant will cause the thorough destruction of media product.Suppose that a reader has downloaded the works of digital library's issue on the net, print and illegally distribute in a large number to seek interests, the works that comprise so watermark should be able to still provide enough copyright evidences in the situation that having physical distortions.Digital watermarking classification: for the classification of digital watermarking, have different criteria for classifications: (1) is divided from visual angle: be divided into visible watermark, invisible watermark.As its name suggests, be exactly with after embed watermark, can by people, be take naked eyes identification watermark be according to dividing; (2) from watermark embedded location, divide: time (sky) territory digital watermarking, frequency domain digital watermark, the watermark of time/frequency domain digital and the digital watermarking of time/scale domain.(3) from robustness, divide: robust watermarking, complete fragile watermark, semi-fragile watermarking.
In addition, digital signature is introduced.Digital signature is exactly the hop count word string that others that only have that the sender of information could produce cannot forge, and this hop count word string is also the sender of information to be sent to valid certificates of information authenticity simultaneously.Digital signature is the application of asymmetric-key encryption technology and digital digest technology.Digital signature the integrality of file be easy to checking, and digital signature has non repudiation.Briefly, so-called digital signature is exactly some data that are attached in data cell, or the cryptographic transformation that data cell is done.This data or conversion allow the recipient of data cell in order to confirm the source of data cell and the integrality of data cell protected data, prevent from for example, being forged by people (recipient).It is a kind of method that the message of electronic form is signed, and a signature information can be transmitted in a communication network.Based on public-key cryptosystem and private key cipher system, can obtain digital signature, be mainly the digital signature based on public-key cryptosystem.Comprise ordinary numbers signature and special number signature.Ordinary numbers signature algorithm has RSA, ElGamal, Fiat-Shamir, Guillou-Quisquarter, Schnorr, Ong-Schnorr-Shamir Digital Signature Algorithm, Des/DSA, ECDSA (Elliptic Curve Digital Signature Algorithm) and finte-state machine Digital Signature Algorithm etc.
It should be noted that the present invention does not limit the position of digital rights information, quantity and existence form.As mentioned above, can adopt for example existing digital watermarking algorithm, for specific user's fingerprint generates unique user ID, thereby realize digital rights information.
With an instantiation, the present invention is described in detail below.
For example, certain user uses a smart mobile phone, and he wants in photo, to add personal and digital watermark when utilizing mobile phone photograph (video recording), to during photo, show that photo from his hands in issue afterwards.This user signs in to after mobile phone by fingerprint recognition system, and fingerprint recognition system has recorded his fingerprint.When this user uses the inventive method first, mobile phone can eject user's configuration block, and by configuration parameter is set, mobile phone generates his fingerprint and the corresponding relation of user ID automatically, and preserves.Herein, mobile phone can, by generating digital watermarks such as existing digital watermarking algorithms, not repeat the generative process of digital watermarking herein.When this user after this or next time uses mobile phone, if (this function can arrange by mobile phone to add the function of watermark while having started according to of the present invention taking pictures, for example, be set to " while taking pictures, acquiescence is added watermark "),, whenever this user presses while taking pictures key, mobile phone automatically extracts the digital watermarking that this user fingerprints is corresponding and adds in photo.
For another example, when user opens mailbox editor new mail on mobile phone, mobile phone is automatically transferred the user ID that this user fingerprints is corresponding and is added in mail, user ID herein can be the signing messages of forms such as " name+address+phones ", namely in this example, user ID is editable text, and when generating new mail, automatic powder adding is added in mail.Certainly the user ID in this example can be also image or other modes.
