Description of drawings
Fig. 1 is the data safety processing method process flow diagram of the embodiment of the invention;
Fig. 2 is the data safe storing equipment synoptic diagram of the embodiment of the invention.
Embodiment
Embodiment one
Referring to accompanying drawing 1, be the data safety processing method process flow diagram of the embodiment of the invention.The data safety processing method of present embodiment comprises registration process and use two large divisions; Wherein registration process comprises step 101 to step 103, and use comprises that step 104 is to step 108.
Most biological characteristic can be by optical sensor such as CCD or CMOS formation picture signal, such as fingerprint, palmmprint, face etc.; But, need infrared light supply just can obtain details feature clearly for iris.Present embodiment is by gathering above-mentioned biological characteristic with the corresponding physical characteristics collecting equipment of gathering of biological characteristic.Each biological characteristic has the characteristics of self, such as, fingerprint characteristic is that wherein details refers to the point of crossing or the end points of ridge based on the feature of the details formation of a succession of ridge, ditch and the finger surface of finger surface; Facial characteristics is the space geometry relation based on facial key feature, measures with the distance between eyes, nose, the lower jaw limit etc. usually; Iris feature is based on the formed pattern of iris, i.e. coloured moiety in the eyeball.
Above step has been finished the registration process of user at data safe storing equipment, and following steps are used data safe storing equipment for the user, the use that the data that equipment is preserved are operated.
Each user has self unique biological feature, gather as step 101 and step 104 couple same user, then first biometric templates and second biometric templates are complementary, the user of description of step 104 is the registered user, this user has the authority of using data safe storing equipment, can operate device data.
If first biometric templates or second biometric templates are complementary, the content that they are described is identical; Use first biometric templates or second biometric templates that data are carried out encryption and decryption, their effect is identical.In the present embodiment, earlier with biometric templates initialization storage data encrypting and deciphering unit, by storing the data encrypting and deciphering unit, the data that flow out equipment are decrypted processing then, make the data that are kept at the equipment the inside be in encrypted state the data that flow into equipment are carried out encryption.
Because deciphering, device data encryption and decryption etc. are stored and read to biometric templates extraction and coupling, biometric templates all in the inner realization of data safe storing equipment as the encryption of key, it is invalid that general communication deception will become, the opponent will crack this equipment, need pay chip analysis or the above cost of equal rank.And in the present embodiment, biometric templates can be saved in movable storage device, i.e. biometric templates off line keeping uses this biometric templates ciphered data can be considered to as safe as a house in the equipment.In case of necessity, legal registered user has the right to change or destroy this key, and makes the data complete failure of device storage.
The technical program not only uses biometric templates to realize the safe access control of data safe storing equipment; and use biometric templates that device data is carried out encryption and decryption and handle; make the data that are kept at the equipment the inside be in encrypted state; realize duplicate protection by biometric templates, thereby improve the safety of device data.
Existing as follows to the plain text encryption mode, when equipment making, work out a series of keys that are used for data encryption in advance, and when the user registers, select one of them at random.After authentification of user passed through, equipment was read key selected when registering from the key memory block, and finished the encryption and decryption processing of data.Because these keys are predefined, therefore can obtain by stealing the device design data; Because these keys are to select from fixing memory block, pool of keys, therefore its limited amount can crack by the mode of storage area data analysis and exhaustive all memory block keys, and then obtains the plaintext of device storage data.And in the technical program, directly with the encryption and decryption key of biometric templates as data, when equipment making, do not work out any data encrypting and deciphering key in advance, belong to this user and equipment and only when the user registers, produce, unique (non-unification) data encrypting and deciphering key, it all is unique making the encryption and decryption key of each equipment with this, prevents to obtain key by stealing the device design data, prevent by the exhaustive key that cracks of key, thereby improve security.
As an alternative embodiment of the invention, be with the foregoing description difference, in step 103, directly preserve first biometric templates of not encrypting, promptly do not need encrypting step; Accordingly, in the step 106, obtain first biometric templates of not encrypting, promptly do not need decryption step.Consider and first biometric templates can be kept at movable storage device, when not using this first biometric templates, can disconnect being connected of movable storage device and data safe storing equipment, and movable storage device is placed on safe place; Even, can not cause too much influence to safety in utilization so first biometric templates that is stored in movable storage device is not encrypted yet.
