An intelligent contract is an application running on a blockchain platform built from distributed blockchain servers. And the authorization terminal equipment uploads the plurality of seal patterns to the intelligent contract. After receiving the seal application sent by the application terminal equipment, the authorization terminal equipment preliminarily examines whether the seal application meets the seal use condition, and if the seal application does not pass the preliminary examination, the authorization terminal equipment sends the information rejected by the preliminary examination to the application terminal equipment through the distributed block chain server; if the initial examination is passed, respectively sending the information passed by the initial examination to the application terminal equipment and the intelligent contract through the distributed block chain server, retrieving the internal storage of the intelligent contract to obtain a specific seal pattern corresponding to the current seal application, randomly generating coding information, and sending the coding information and the specific seal pattern to the application terminal equipment through the distributed block chain server; a communication module 402 of the stamp stamping machine receives the coding information and the specific stamp pattern sent by the application terminal equipment, and a secret key storage module 405 receives and decrypts the coding information and the specific stamp pattern sent by the communication module 402; the key storage module 405 and the stamp generator 200 are connected through the central processor module 401, and the stamp generator 200 generates a stamp with the encoded information and the specific stamp pattern according to the received encoded information and the specific stamp pattern.
When the stamp generator 200 does not receive the coded information and the specific stamp pattern after the stamp application passes, the stamp generator 200 is in an initial state, and any stamp pattern or coded information can not appear when the stamp stamping machine is pressed; upon receiving the encoded information and the particular seal pattern, the bottom surface of the stamp generator 200 generates a stamp with the encoded information and the particular seal pattern, and the pressing stamp may present authorized encoded information and the particular seal pattern.
Because the coded information is generated randomly and instantly when the seal is authorized after the seal application is passed, each coded information records the authorization information of the specific seal at a specific moment, namely, the coded information has uniqueness and dynamics. Uniqueness means that the coded information of different seals is different, and dynamism means that the coded information authorized to be generated at different times by the same seal is different. This coding information is for can the recognition information, has anyone of the demand of seeking evidence to the true and false of seal, all can open this coding information of camera scanning with the terminal equipment who installs software or plug-in components supporting with the stamp seal machine, retrieves the authenticity of verifying this coding information and seal pattern and the corresponding key data who applies for the mandate with the seal from the block chain, can satisfy the security and the convenience requirement that the seal used simultaneously.
The intelligent contract can store a plurality of seal patterns, and because specific seal patterns correspond to the seal application, the coding information is generated randomly when the seal application passes, and the stamp seal machine can generate different coding information and specific seal patterns according to different seal applications of the application terminal equipment, thereby realizing remote seal application and authorization work of a plurality of different seals. Only one stamp stamping machine is needed, the requirement of managing a plurality of stamps by individuals or units can be met, remote stamping application and authorization work of the plurality of stamps is achieved, and economic cost and management cost are greatly reduced.
The stamp generator 200 includes a thermosensitive material film 2012, a micro-heater 2013 disposed above the thermosensitive material film 2012, and a driving circuit 2014 for controlling heating of the micro-heater 2013, and the driving circuit 2014 is connected to the cpu module 401.
Specifically, the stamp generator 200 includes a generator housing 2011, a thermosensitive material film 2012 disposed at the bottom of the generator housing 2011, micro heaters 2013 accommodated inside the generator housing 2011 and located right above the thermosensitive material film 2012 and closely arranged in a lattice manner, and a driving circuit 2014 disposed inside the generator housing 2011 and connected to the micro heaters 2013 arranged in a lattice manner.
The micro heating bodies 2013 are arranged right above the thermosensitive material film 2012 and are uniformly, tightly and tidily arranged on a plane in a dot matrix mode, and the micro heating bodies 2013 are uniformly controlled by the driving circuit 2014 and are used for heating and stimulating the thermosensitive material film 2012.
In this embodiment, the micro heater 2013 is a nano titanium electric heater or a PTC micro constant temperature electric heater.
Compared with the electronic seal in the prior art, the solid seal generated by the seal generator 200 can be directly stamped on a paper document, and the traditional seal using mode of people is more met. The material at the local position of the thermosensitive material film 2012 is heated by the micro heating body 2013 and expands and bulges due to the principle of expansion with heat and contraction with cold, the thermal conductivity of the thermosensitive material film 2012 is poor, and when the material at the local position is heated and bulges, the surrounding material cannot expand and bulge in a short time, so that an authorized stamp with coded information and a specific stamp pattern is generated; after the stamping is finished, the micro heating body 2013 stops heating, and the part of the thermosensitive material film 2012 is changed into a flat state again from a bulge. Therefore, the thermosensitive material film 2012 can generate any encoded information and specific stamp patterns, and only one stamp stamping machine is needed to realize management of multiple stamps or remote stamp application and authorization of multiple stamps, so that the economic cost and the management cost are greatly reduced.
In this embodiment, the thermosensitive material film 2012 is a polyurethane aerogel film. Polyurethane aerogels are very elastic, meaning that they can be bent in any direction or collapsed and still return to their original shape. Professor of chemistry at the university of technology, micholas Leventis, indicates that these superalastic aerogels differ from rubber in that they can be brought back to a specific shape on command, i.e., exhibit strong shape memory properties, meaning that they can permanently retain their deformed shape after deformation and cooling.
And the driving circuit 2014 is used for connecting and controlling the micro heating bodies 2013, and systematically controlling the working state of each unit of the micro heating bodies 2013 arranged in a lattice in real time by receiving the coding information and the specific seal pattern sent by the central processing unit 401. The number of micro heaters 2013 is related to the stamp size and the definition of the stamp pattern, the higher the lattice density of the micro heaters 2013, the higher the stamp precision generated by the stamp generator 200, i.e. the clearer the stamped stamp pattern, the lattice density of the micro heaters 2013 on the stamp plane is between 1/square centimeter [1 ÷ (1 × 1) ═ 1 (pieces/square centimeter) ] and 14400/square centimeter [ (120 × 120) ÷ (1 × 1) ═ 14400 (pieces/square centimeter) ], wherein the maximum lattice density of 14400/square centimeter is approximately equal to the general printing precision of a common printer of 300 dpi; typically, the stamp is a circle having a diameter of 60 mm, the lattice density of the micro heaters 2013 on the plane of the stamp is 1600/cm [ (40 × 40) ÷ (1 × 1) ═ 1600 (per square cm) ], the number of micro heaters 2013 required per english or numeric character is 7 × 9 lattice, and the number of micro heaters 2013 required per kanji character is 12 × 16 lattice.
The coded information is a one-dimensional code or a two-dimensional code.
The one-dimensional codes or the two-dimensional codes comprise coded information generated immediately when the seal is authorized, each one-dimensional code or each two-dimensional code only points to the authorized information of the specific seal at a specific moment, namely, the one-dimensional codes or the two-dimensional codes have uniqueness and dynamism, the uniqueness means that the coded information of the one-dimensional codes or the two-dimensional codes of different seals is different, and the dynamism means that the coded information of the one-dimensional codes or the two-dimensional codes generated by the same seal at different moments is different.
Because the one-dimensional code or the two-dimensional code can be read by a specific device. Anyone who has the requirement of asking for evidence to the true and false of seal can open the attached one-dimensional code of this seal of camera scanning or two-dimensional code with the terminal equipment who installs supporting software of stamp seal machine or plug-in components, retrieves the authenticity of verifying this one-dimensional code or two-dimensional code and seal pattern and the key data who authorizes with the seal application that corresponds from the block chain, can satisfy the security and the convenience requirement that the seal used simultaneously.
Preferably, when the encoded information is a one-dimensional code, the one-dimensional code is disposed around the stamp pattern.
Because the one-dimensional code is a mark formed by a group of regularly arranged bars, spaces and corresponding characters and is usually in a strip shape, the one-dimensional code is arranged around the seal pattern, for example, when the seal pattern is circular, the one-dimensional code is externally encircled on the seal pattern to form an arc-shaped structure, the overall layout of the seal pattern is not influenced, the overall length of the one-dimensional code is reduced, the overall size of the seal is favorably reduced, and the overall layout is convenient.
The stamp of the one-dimensional code outer ring stamp pattern generated by the stamp generator 200 comprises a stamp of a traditional stamp pattern and a stamp of a one-dimensional code outer ring matched with the outline of the traditional stamp pattern. The stamp of the one-dimensional code outer ring stamp pattern is a convex stamp or a plane stamp. When the stamp generator 200 does not receive the authorized one-dimensional code outer ring stamp pattern, the stamp generator 200 is in an initial state, and any stamp pattern and one-dimensional code cannot appear during pressing and stamping; after the one-dimensional code outer ring seal pattern is received, the bottom surface of the seal mold generator 200 generates a seal mold with the one-dimensional code outer ring seal pattern, and an authorized one-dimensional code outer ring seal pattern can appear by pressing and sealing.
A positioning module 403, a pressing detection module 407 and a camera module 300 which are respectively connected with the central processor module 401 are arranged on one side of the stamp generator 200, wherein the positioning module 403 is used for detecting the position information of the stamp stamping machine in real time; a pressing detection module 407, configured to detect whether a pressing seal action is performed and record the number of times of performing the pressing seal action; the camera module 300 is connected to the communication module 402, and is configured to scan and photograph the sealed paper document, and record a seal witness video during the sealing process.
Specifically, the intelligent control circuit 400 further includes a storage module 404, a pressing detection module 407, and a positioning module 403 connected to the central processor module 401.
The storage module 404 is used for storing basic program codes and drivers of the stamp stamping machine, temporarily storing the stamping witness video recorded by the camera module 300, and temporarily storing the cache and temporary files generated by the central processor module 401.
The pressing detection module 407 is configured to detect whether a pressing seal action is performed and record the number of times of performing.
