Description
Technical field
The present invention relates to a kind of internal storing memory and data guard method thereof with fingerprint sensing function, particularly a kind of mode with fingerprint sensing is reached the storage device and the method thereof of file data protection purpose.
Background technology
At present generally in order to the practice of secret personal data, the protected mode that accesses to your password is usually protected personal data yet access to your password, trouble, the danger that more has password cracked by the people such as not only easily cause that the user forgets Password.
Therefore; use individual biological data; biological identification methods such as fingerprint, vocal print, person's handwriting, iris for example; its advantage is that biological characteristic is the part of human body, must not remember especially, more can't be stolen; especially in conjunction with the guard method of fingerprint biological characteristic; not only tight, and quite convenient on using, so be developed into complete gradually and the active data protected mode.
As No. the 6213403rd, United States Patent (USP); No. 6213403; No. the 2003/005337th, U.S. Patent Publication; world patent WO 02/42887A; patents such as European patent EP 124079A1 and BrP GB2387933 number; a kind of data that in this device, are stored in internal memory inside by the identification of fingerprint protection have all equally all been disclosed; it still is similar to the United States Patent (USP) storage device with fingerprint sensor that No. 4582985 communique disclosed, and disclosed identification of fingerprint framework mainly all is a fingeprint distinguisher (being that fingerprint acquisition and identification all are to carry out in same device) independently.
