Embodiment
Such as a possible application scenarios (be used to strengthen this technology understanding):
The user of 3G mobile who possesses this function is under attack, recorded one section DV that the suspect attacks immediately with mobile phone, simultaneously owing to contain the GPS receiving chip (if do not have in the mobile phone, communication network also can provide corresponding Position Approximate and time), so mobile phone can obtain on-site information and can obtain temporal information, when taking DV, mobile phone will take on-site latitude and longitude information by certain cryptographic algorithm automatically and temporal information is incorporated among this section DV that records, even this section DV is exported in the PC, also be difficult to the DV of this section shooting is made amendment, and, setting according to the machine master, mobile phone also in real time by 3G transmittability at a high speed with these transfer of data in server, server is by detecting the sub-district at the also comprehensive mobile phone place of encryption mechanism wherein, the comparison of aspects such as base station time, confirm the authenticity (promptly not through the property revised) of this section DV, server is stored in it in corresponding database simultaneously.Simultaneously, according to machine master's setting, this mobile phone sends the request of reporting to the police automatically, and then server is also from being dynamically connected 110 alarm stations, and corresponding information is offered the police service center.Rescue and investigation work are launched according to corresponding information in the police service center.
Use the inventive method in the daily social management: to handing over rule violator's evidence obtaining, city management division management person is to city management rule person's evidence obtaining in violation of rules and regulations as the traffic police.
Concrete scheme flow process following (being example) to use the MD5 algorithm, as shown in Figure 1, 2:
When obtaining A, obtain S pairing temporal information B and positional information C in the time, A, B, C carried out integrated, form A ', A ' is carried out the MD5 computing, MD5 value m, A ' and m together are transmitted through the network to server F, F obtains A " and m.F is to A " carry out the MD5 computing, obtain m ',, then A ' and A if m is identical with m ' " the identical A of being ' may not be modified; If m is different with m ', then A ' and A " different, promptly A ' was modified.Server obtains corresponding temporal information B ' from system or the GPS that carries, server reports acquisition relevant terminal positional information C ' from the GPS of system or terminal, through the comparison of same B, C, if in reasonable range, then can be near assert that A ' did not revise utterly; If exceeding reasonable range, then need further to analyze and assert whether A ' was modified.
Server obtains corresponding temporal information B ', server from system or the GPS that carries and reports from the GPS of system or terminal and obtain relevant terminal positional information C ' if in reasonable range, then can then need further to analyze and assert whether A ' was modified near assert A ' if be not revise exceeding reasonable range utterly
For encryption class algorithm (in fact can be called as checking algorithm) mentioned above, at present commonly used as MD5, the RSA scheduling algorithm.Use such algorithm can be undertaken whether the electrical type media file that corresponding verification computing confirms that terminal is obtained is original document (being modified) by the server of local side.
About the flow process of automatic warning,, no longer further give unnecessary details at this because very simple.
The algorithm characteristic introduction of MD5:
MD5 is a kind of checking algorithm commonly used, and any e-file can draw a unique MD5 value by this algorithm computation, and is if promptly original document is carried out any modification, then identical scarcely with source file by the MD5 value that amended file calculated.As long as source file and the MD5 value of calculating gained are together sent, the side after then receiving also carries out MD5 to the file of receiving and calculates in use, if gained MD5 value is identical with the MD5 value of receiving, the file of then receiving is the file of not revising.
Judge the reliability diagram that is not modified after the electrical type data encryption to using this kind method:
Because under this kind method situation, electrical type data A if former data are modified, then must can not get same m through after the same computing through obtaining after the computing and former data summary data m one to one.So if through comparing, if different, then the data that obtain after the transmission necessarily were modified m with m '.For caution's sake, if more corresponding again position temporal informations etc. then can obtain being close to absolute conclusion.
So all can be made a summary or the algorithm of verification to data, all can use in this way, as MD2, MD4, MD5 serial algorithm, HASH serial algorithm, CRC series checking algorithm etc.
Also can use other algorithms (being example) with RSA Algorithm, as shown in Figure 3: when obtaining a, obtain S pairing temporal information b and positional information c in the time, carry out integrated to a, b, c, form a ', with the PKI m of RSA Algorithm to a ' encrypt a "; with a " and m together be transmitted through the network to server F, F obtains A and m.F is decrypted computing with corresponding RSA private key n to A, obtains A '.Server obtains corresponding temporal information b ' from system or the GPS that carries, server reports acquisition relevant terminal positional information c ' from the GPS of system or terminal, relatively appended time location information b, the c of A ' if in reasonable range, can assert tentatively that then A ' did not revise; If exceeding reasonable range, then A ' was modified probably.Need comprehensively to do further to analyze in conjunction with other information that A ' provided, as the continuity of image, sound, the continuity of literal semanteme etc.If judge that through comprehensive the information of A ' expression is reasonable, then can assert that A ' was not modified in highly probable property ground; If judge that through comprehensive the information of A ' expression is unreasonable, then can assert that A ' was modified in highly probable property ground.
Judge the reliability diagram that is not modified after the electrical type data encryption to using this kind method: because under this kind method situation, if the electrical type data do not have private key n through encrypting the back, then can't decipher and know the electrical type data of being encrypted, therefore the modification of encrypting back information is very likely caused the non-reasonable change of encrypted file, so after deciphering, will be easy to be discovered.Therefore, this kind method can be highly probable the property ground data that determine to obtain through transmission whether for being modified.
So the algorithm that all can be encrypted data as long as decrypted difficulty is enough, all can use in this way, as being the symmetric encipherment algorithm of representative with EDS, AES, or RSA, asymmetrical public key algorithm such as ECC etc.
