An authenticity indicator is difficult to be forged and has an authenticity that can be confirmed easily and accurately. The authenticity of the authenticity indicator can be checked by making light enter the authenticity indicator from front side and observing the light emerging from the front side or rear side. The authenticity indicator includes a polarized-light selectively reflecting layer that reflects a specified polarized component of incident light, and a transmission volume hologram layer disposed on the front side of the polarized-light selectively reflecting layer. According to this authenticity indicator, its authenticity can be checked accurately by making use of its first authenticity recognition function attributed to the diffracting action of the transmission volume hologram layer and its second authenticity recognition function attributed to the polarized-light selectivity of the polarized-light selectively reflecting layer.

The invention aims to provide a process control method, apparatus and system. The method comprises the steps of obtaining an I / O request package sent by an operation system through the process control apparatus, wherein the I / O request package is generated by an I / O manager when an application is started; querying content identifier information of a process file corresponding to the I / O request package, wherein the content identifier information is generated based on contents of the process file; and when the matched content identifier information is queried, allowing the process file to run. A white list in the prior art generally stores names of process files, and as long as the names are same, processes are trusted processes, so that the processes are very easily counterfeited. Compared with the prior art, the process control method, apparatus and system has the advantages that the content identifier information of the process file needs to be checked before process running, and if the content identifier information is not in the white list, the process file is not allowed to run, so that hackers cannot counterfeit the trusted processes and whether the processes are the trusted processes or not can be accurately identified.

The invention relates to an identity authentication method and system for performing space-time uniqueness and continuity judgment. On the basis of big data rule analysis, unreasonable situations can be deduced according to existing rule calculation instead of exhaustion of all unreasonable situations in advance. Just like the game of go, on the basis of a chess manual, regular and reasonable judgment conclusions can be deduced automatically according to chess playing conditions. By means of the automatic deduction method, any counterfeiting and sneaking behaviors needing to be forewarned can be found in an almost non-dead-corner and non-loophole mode. The space-time uniqueness and continuity concept is adopted, in other words, the real identity of a doer is unique, the real doer should be in the unique location at a certain time, locations should be connective in the continuous time progress, and habit rules also exist on the basis that behaviors are executed at the certain time possibly or can be roughly deduced according to other information.
