400 perform deformation successively passes ginseng code block 401, new entry code block 402 and return value encryption function module 403, performs simultaneously
The removing 501 of API name is to remove API name 301, and then generates the file after protection, i.e. realizes the safeguard protection of application platform；
Step S62: when performing to be worth 305 to API return, the trap instruction 503 pre-set is triggered, and jumps into sunken subsequently
Trap processes deciphers return value encryption function module 403 in function, and then in the presence of can determine whether the return value of deciphering and program
API deciphering return value is the most corresponding, if so, forwards step S63 to, otherwise forwards step S64 to；
Step S63: API response message is sent to computer server by software application platform 200, scientific research personnel obtains required
The user's brain electric information wanted；
Step S64: authentication failure message is sent to computer server by software application platform 200, stops API response.
Clerk personnel carry out needing the side of safety certification when calling, by software application platform 200, the EEG signals collected
Method, had both facilitated scientific research personnel's extraction to EEG signals, can prevent again assailant from stealing the health and fitness information of user, it is ensured that to make
The safety of user's health and fitness information.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, it is also possible to make some improvements and modifications, these improvements and modifications are also
Should be regarded as protection scope of the present invention.
