Description
Technical field
The invention relates to a kind of communication technical field, the method for proof of particularly a kind of proof system of mobile phone record length and mobile phone record length.
Background technology
Nowadays, the sound-recording function module is as basic configuration, and is widely used in the mobile phone, makes people to remain as judicial evidence by the dialog context that part is important.But the mobile phone recording file can be afterwards by artificial modification owing to being to be retained on the user mobile phone, and its authenticity also just has problem.
Chinese patent application CN101005534A has disclosed the method that a kind of telephone terminal is realized recording function of telephone.Referring to Fig. 1, be the signaling process figure that telephone terminal is realized recording function of telephone, this method comprises calling record process and recording leaching process, the calling record process comprises: (1) the user sound-recording business that puts telephone lines into operation; When (2) user with telephonograph business called out, the user attaching local switch called out this to switching value recording switching plane by the communication protocol of agreement; (3) recording switching plane communication protocol is by appointment called out this and is submitted to voice server to handle, and by the recording switching plane this calling is forwarded to the switch at this user place then, and the calling and called both sides begin conversation; (4) voice server communication protocol by appointment begins recording; After either party terminated call of calling and called, voice server finishes recording and user's recording is stored in the voice server again; The recording leaching process comprises: realize alternately by user and voice server.
But the recording as judicial evidence will have objective and accurate timeliness, and this just need provide time calibrating for the recording of recording, and makes it have the proof function of the site of the accident.Because the recording of existing mobile phone can not be for recording provides objective and accurate time calibrating, thereby the mobile phone recording often can not prove when the thing condition as positive evidence, also must be by other identity means, and as the witness etc.
Chinese patent application CN101005709A discloses the method for proof of a kind of mobile phone photograph time.Please refer to Fig. 2, Fig. 2 is the flow chart of the mobile phone photograph time-proven method of prior art, this method comprises: the user starts mobile phone photograph proof module, press the shutter of taking pictures after choosing the object of taking pictures, when the user presses the shutter of taking pictures, mobile phone is to the instruction of mobile network's transmitting time proof, the mobile network identifies the time-proven instruction, send proof command reception receipt to mobile phone, mobile phone extracts the time on date when taking pictures automatically from receipt, and is inserted in institute's picture of taking a picture, when the user preserves photo, and be inserted in institute's picture of taking a picture, when the user preserved this photo, mobile phone sent to mobile network's photo preservation center with a copy of photo, after this preservation center receives photo, the preserving number of a displacement is provided for this photo, preserving number is beamed back user mobile phone, and for photo adds descriptive information automatically, and photo and descriptive information thereof are set to read only attribute, be saved in preservation central server database, for other people visit.
But, this method with whole photo upload to third-party server, not only wasting space but also increased the message transmission time.This external with photo upload when the third-party server not to the checking of uploader identity, also have leak in the assurance of its objectivity.
Summary of the invention
The purpose of this invention is to provide a kind of mobile phone record length proof system and method, can prove the authenticity of mobile phone record length, become possibility as judicial evidence so that will have the mobile phone recording of authenticity.
For achieving the above object, the invention provides a kind of mobile phone record length proof system, this system comprises a mobile phone and a server at least, described mobile phone comprises recording module, functional operation module and data memory module; Described server comprises data storage device; Described recording module recorded voice evidence sends the information of request notarization simultaneously to described server; Described server verifies to mobile phone that promptly described mobile phone obtains correct time information at that time from described server after by checking; Described mobile phone writes this temporal information in the recording file after End of Tape, and the identification code by described functional operation module generation recording file is saved in described data memory module with described recording file and identification code; Described mobile phone uploads to described identification code in the described server, and described server saves as the notarization record with above-mentioned information together with described time recorded information, and the record of will notarizing accordingly sends to described mobile phone.
For reaching above purpose, the present invention also provides a kind of method of proof of mobile phone record length, sends the notarization solicited message to server when comprising the following steps: that mobile phone begins to record; Described server is verified described mobile phone; After checking was passed through, described server sent current time information as the time recorded information to described mobile phone, and should the time recorded information in described server stores; Described mobile phone receives this time recorded information, and should the time recorded information write recording file behind End of Tape, stores this recording file at described mobile phone then; Described mobile phone generates an identification code of this recording file, preserves this identification code, and this identification code is uploaded to described server; This identification code that described server will receive is preserved into a notarization record together with this time recorded information, and recording mechanism that will this just record sends to described mobile phone.
The invention has the beneficial effects as follows thus: can prove the authenticity of mobile phone recording substance and the authenticity of mobile phone record length,, increase a kind of new lawful evidence presentation mode so that the mobile phone recording becomes possibility as lawful evidence.
