Description
Technical field
This specification is related to fingerprint identification technology field, more particularly, to a kind of data processing method, OTA client, electricity
Sub- equipment and storage medium.
Background technique
It is wireless that over the air (Over-the-Air, abbreviation OTA) refers to that electronic equipment (such as mobile terminal) passes through
Network downloads the upgrade package on remote server, to the technology that system or application are upgraded, by the working procedure in hardware
Or source code improves, it is made to obtain compatibility, performance or raising functionally.
For the fingerprint recognition system of electronic equipment, after OTA upgrading, it shall be guaranteed that version and old version after upgrading
This holding compatibility, already present finger print data are still normal (such as: the fingerprint of typing still has, and can be with normal release).
During realizing the application, the inventor of the present application discovered that: when OTA upgrades fingerprint algorithm every time, need and
Version before keeps compatibility, such as when fingerprint algorithm is upgraded to algorithm B from algorithm A, it is necessary to keep B can be with
Compatible A, i.e. A is a subset of B, and the fingerprint function after being just able to maintain OTA upgrading in this way is normal, this will give fingerprint algorithm band
Limit to, limits the efficiency of fingerprint algorithm.Moreover, if algorithm A is not the subset of algorithm B, in OTA
After upgrading, old fingerprint template data will cannot use that (fingerprint of typing i.e. before customer upgrade unlocks result not after upgrading
Know).Once this occurs, fingerprint template data that generally can only be old in OTA Force Deletion during upgrading, will so destroy
The data of user can bring puzzlement to user.
