Obtained image data scrambled used in scrambled code be host side it is known that therefore, when image data scan process fills
Set after the image data after above-mentioned scrambling is transferred to above-mentioned host side, above-mentioned host side can based on known scrambled code and
Synchronous code is correspondingly descrambled to the image data received and reduction treatment.
Optionally, when carrying out image scanning by imaging sensor every time, the synchronous code from host side is all received,
That is, synchronous code can be all handed down to image data scan process by host side when carrying out image scanning by imaging sensor every time
Device, then image data scaning treatment device is according to preset synchronous code-image scanning sequence correspondence relationship information, according to this
The secondary corresponding image scanning sequence of synchronous code received is scanned each pixel on imaging sensor.In this mechanism
Under, the synchronous code that host side can be made to issue every time is all different from the preceding synchronous code once issued, so that image data
Image scanning sequence when scaning treatment device is every time scanned each pixel on imaging sensor all with it is preceding primary right
Image scanning sequence when each pixel spot scan on imaging sensor is different, and then increases the difficulty that image data is cracked
Degree, improves the transmission security of image data.Correspondingly, host side can be every time under image data scaning treatment device
While sending out synchronous code, data mapping is carried out to above-mentioned synchronous code by above-mentioned first data mapping algorithm, obtains scrambled code.When
So, host side can also be reflected by above-mentioned first data mapping algorithm to when the secondary synchronous code used carries out data on other opportunitys
Penetrate, the process only need to image data after to when the scrambling time received descramble before complete.
Specifically, imaging sensor as mentioned in the embodiments of the present invention is fingerprint sensor, then correspondingly, the present invention is implemented
The image data referred in example is fingerprint image data.Certainly, imaging sensor as mentioned in the embodiments of the present invention may be
Other types of imaging sensor, is not construed as limiting herein.
It should be noted that the image data scaning treatment device in the embodiment of the present invention can specifically be integrated in above-mentioned image
In sensor.
Therefore pre-determined synchronization code-image scanning sequence correspondence relationship information in the present invention, on to imaging sensor
Each pixel when being scanned, image scanning sequence corresponding to the synchronous code sent according to host side is scanned, realizes
First level scrambling of image data further carries out the image data that scanning obtains by scrambled code known to host side
Scrambling, realizes the second level scrambling to image data, since the synchronous code and scrambled code are host side it is known that therefore, leading
Generator terminal can be based on the scrambled code and synchronous code is correspondingly descrambled to the image data transmitted and reduction treatment, and right
In other data theft persons, used scrambled code when being difficult to know synchronous code used in scanning and scrambling due to them,
Therefore the difficulty for increasing the image data that stealer's reduction is stolen to a certain extent, at traditional image data
Reason scheme improves the transmission security of image data.
