Step 301, the sign comprise Password Operations instruction and/or encrypted message is set on information carrier authentication zone, described sign also is provided with the coding pattern that naked eyes can't be discerned on the corresponding position, coding pattern can be convenient to described image analysis unit cryptography pattern and cipher mark are separated with different printing ink settings with corresponding cipher mark.
When step 302, recording device were started shooting at every turn, the output function of its audio file was under an embargo.
Step 303, the user authentication password that judges whether to reset, if, enter step 304, if not, enter step 308.
" modification password " and/or " current password " Password Operations command identification in the writing unit click information carrier authentication zone of step 304, recording device.
The cipher mark in step 305, writing unit click information carrier authentication zone comprises and clicks Digital ID, character mark, symbol logo, and a plurality of signs of click are formed user's original password sign or current password sign.
" new password " sign in step 306, writing unit click information carrier authentication zone.
The cipher mark in step 307, writing unit click information carrier authentication zone, comprise and click Digital ID, character mark, symbol logo, a plurality of signs of clicking are formed user's new password sign, and new password is current password, enters step 309 afterwards.
The sign in step 308, writing unit click information carrier authentication zone comprises and clicks Digital ID, character mark, symbol logo that a plurality of input cipher marks of click are formed user's current password sign.
Step 309, image acquisition unit obtain the image of current password sign, and the image analysis unit separates the coding pattern that obtains current password sign and current password from the image that obtains, and further the coding pattern parsing are obtained information code.
Step 310, password comparing unit judge whether the current password sign of input cipher mark and storage is identical, judge perhaps whether the current password coded message of input cryptography information and storage is identical; If identical, enter step 311; If difference enters step 312.
Step 311, recording device can export the audio file of recording from recording device by opening the audio file output order.
Step 312, recording device are kept and are forbidden that the recording audio file exports to outside device, can also return step 303 simultaneously.
The invention provides recording system, recording device and audio-frequency inputting method, do not influence recording of audio file, only limit the output of audio file with identity authentication function, also can the recording audio file even do not do authentication; But have only by authentication, could put the audio file of recording outward, the audio file transmissions of recording is arrived recording device other devices in addition with recording device; Concerning according to the click type recording device of the output of the sign on information carrier respective audio file, be a kind of auth method very easy to use.
Should be understood that above-mentioned statement at preferred embodiment of the present invention is comparatively detailed, can not therefore think the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with claims.
