When the temporal location information and the spatial location information are complete information, it may be determined that the electronic data information has not been tampered with or intercepted.
In the method provided by the embodiment of the invention, whether the electronic data information is effective information is determined by judging the time information and the space position information contained in the space-time information. Therefore, when the electronic data information is used as anti-counterfeiting evidence, the reliability and credibility of the anti-counterfeiting evidence are ensured.
In the method provided by the embodiment of the present invention, when the acquisition device acquires electronic data information, acquiring original spatiotemporal information currently recorded by the navigation device corresponding to the acquisition device, specifically includes:
acquiring an exposure time pulse corresponding to the electronic data information and a PPS time pulse of the navigation equipment, and carrying out clock synchronization on the exposure time pulse and the PPS time pulse to acquire synchronized clock information;
and adjusting the current time information and the current space position information of the navigation equipment according to the synchronous clock information to obtain the current recorded original space-time information of the navigation equipment.

and calling a preset interleaving coding technology, interleaving an information code stream corresponding to the original space-time information with the electronic data information from the header position of the electronic data information, and embedding the information code stream into the electronic data information.
In the electronic evidence anti-counterfeiting method provided by the embodiment of the invention, after the terminal equipment obtains the original space-time information, the information code stream corresponding to the original space-time information is obtained according to the original space-time information, the information code stream corresponding to the original space-time information is firstly placed at the information header of the electronic data information by calling a preset interleaving coding technology, and is interleaved with the electronic data information from the header position of the electronic data information, and the information code stream corresponding to the original space-time information is embedded into the electronic data information. The code stream corresponding to the original time-space information and the electronic data information can be interleaved according to a preset interleaving coding rule, and when the information code stream corresponding to the original time-space information is embedded into the electronic data information, the electronic data information can be considered to be encrypted.
It should be noted that, when the interleaving coding technology is invoked to embed the original spatio-temporal information into the electronic data information, a preset interleaving coding rule may be used to interleave the information code stream corresponding to the original spatio-temporal information. For example, a certain number of interleaving times is set, and interleaving of each row and each column is performed according to the number of interleaving times, wherein the larger the number of interleaving times is, the more complicated the interleaving encoding rule is. By using the interleaving coding technology, the information code stream corresponding to the original space-time information is completely embedded into the electronic data information, so that the electronic data information can be encrypted.
Optionally, during the process of embedding the information code stream corresponding to the original spatio-temporal information into the electronic data information, interleaving may be performed from any position of the electronic data information, or interleaving may be performed from a header of the electronic data information.

In the method provided in the foregoing embodiment, matching the spatiotemporal information with pre-stored original spatiotemporal information specifically includes:
and when the spatiotemporal information is not consistent with the original spatiotemporal information in a matching way, the electronic data information is characterized to be forged, and the forged electronic data information is cancelled.
In the method provided by the embodiment of the invention, when the spatiotemporal information is matched with the original spatiotemporal information to determine whether the electronic data information is forged or not, a preset interleaving coding technology can be called to extract the spatiotemporal information from the electronic data information and match the spatiotemporal information with the original spatiotemporal information. And when the matching is consistent, determining that the electronic data information is valid. And if the spatiotemporal information is inconsistent with the original spatiotemporal information in a matching way, the electronic data information is proved to be forged, namely the electronic data information is falsified or intercepted by other users. When the electronic data information is forged, the electronic data information cannot be used as anti-counterfeiting evidence to form a spatiotemporal evidence chain with other evidence, and meanwhile, the terminal equipment can cancel the forged electronic data information.
It should be noted that, when the interleaving encoding technique is invoked to extract the spatio-temporal information in the electronic data information, the decoding rule in the interleaving encoding preset in the interleaving encoding technique may be applied to extract the spatio-temporal information from the electronic data information.
Furthermore, when it is required to verify whether the electronic data information is forged, the spatiotemporal information in the electronic data information may also be extracted by invoking the interleaving encoding technique, so as to obtain the spatiotemporal information. It is possible to verify whether the spatiotemporal information is complete and determine that the electronic data information is not forged when the spatiotemporal information is not damaged or the complete spatiotemporal information is identical to the original spatiotemporal information. And if the spatio-temporal information is damaged, namely the spatio-temporal information is incomplete or cannot form effective spatio-temporal information, the electronic data information is proved to be falsified or intercepted, and the electronic data information is forged electronic data information.
When the electronic data information is verified to be falsified, it is possible to verify whether the electronic data information is changed by another user such as falsification or interception during a process of being used as a general purpose. When the space-time information in the electronic data information is extracted by using an interleaving coding technology and the space-time information is determined to be consistent with the original space-time information or the space-time information is complete space-time information, the electronic data information is proved to be not tampered or intercepted.
By applying the method provided by the embodiment of the invention, when the spatiotemporal information is inconsistent with the original spatiotemporal information, the electronic data information cannot be used as an anti-counterfeiting evidence, and a spatiotemporal evidence chain cannot be formed by the electronic data information and other evidences, so that the reliability and the credibility of the anti-counterfeiting evidence are improved.
