Electronic document and carrier mutual authentication method and system

The present invention relates to an electronic document and carrier mutual authentication method and system, and more particularly to how to create a high security link between an electronic document and a carrier, so that the validity and source of the electronic document can be verified; When there is a failure, the electronic file in the vehicle is also invalidated; and how to make the connection between the electronic document and the vehicle reversible, that is, when the vehicle is re-applied, it can automatically reply. The electronic file originally stored in the vehicle.

With the development of the information age, the application of electronic documents has become more and more popular. However, the portability and security of electronic documents still have many problems. For the user, it is only hoped that the electronic file can be carried freely on the vehicle, and when the electronic file is needed, the validity of the electronic file can be proved; and when the vehicle is lost, the load can be ensured. The electronic file inside is not suspected of being stolen.

However, today's practices have many problems. First, there are many electronic documents that cannot be placed in the vehicle, or the electronic files stored in the vehicle are not effective. Under such design, many electronic documents can only be used in paper or other ways. Presentation, not only lack of convenience, but also the possibility of being counterfeited. Second, even if the electronic file can be stored in the vehicle, there is no reliable mechanism to identify the authenticity of the electronic document, and the source of the electronic file cannot be known. The source referred to herein includes the source. The owner of the electronic file and the vehicle on which the electronic file was originally stored. Third, there is no safe and reliable way to know the validity of the electronic file. Therefore, when the electronic file fails, we have no way of knowing it; even if we know that the electronic file has expired, we cannot make the electronic file have been copied and distributed. All versions that go out are invalidated together. Fourth, when the vehicle is lost, the user must re-apply to the electronic document verification end of each electronic file, which is quite inconvenient; in addition, once the vehicle is stolen, the electronic file may It will also be stolen and the original holder will not know.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally successfully developed and applied this document to the mutual authentication mechanism of electronic documents and vehicles.

The purpose of the present invention includes the following items: the validity of an electronic document can be verified; when the vehicle fails, all electronic files in the vehicle will also be invalidated to prevent the electronic file from being stolen; In the case of loss or damage, the user can re-send the electronic file in the original vehicle to the new vehicle as long as the new vehicle is loaded. There is no need to apply and download one by one.

The electronic document and vehicle mutual authentication method and system for achieving the above object includes the following parts: The first part is an application for a vehicle, which can be linked to the holder through a unique identification value; The second part is an application for downloading an electronic file into the vehicle, the holder of the vehicle can hold the electronic file and download the electronic file from the electronic file verification end to which the electronic file belongs; The three parts are to read the electronic file. When reading, the legality of the electronic file can be verified. The last part is that when the vehicle is lost, the electronic file in the original device is automatically restored to the new one. With a mechanism.

The method for mutually authenticating an electronic document and a carrier provided by the present invention has the following advantages when compared with other conventional technologies:

1. The carrier of the present invention only needs to have a basic read/write function. In addition, the carrier includes a unique identification value that must be verified so that the vehicle also has an identity.

2. The original application for the vehicle application of the present invention and the electronic document can be handled separately. (The original electronic document referred to here refers to an electronic document stored in the verification end of the electronic document. The electronic document is positive. The owner of the electronic file is the verification end of the electronic file, and the electronic files of the non-existing electronic file verification end are duplicates. There is no chronological connection between the application for the vehicle and the original application of the electronic document, that is, the original electronic document can exist independently and does not need to be attached to the vehicle. The vehicle and the electronic document have their own life cycles. When the vehicle fails, the original electronic document is still valid, and only the copy of the electronic file in the vehicle is invalid.

3. In the present invention, when the vehicle is deemed to be invalid, all copies of the electronic document in the carrier are also automatically invalidated. Since there is a mutual authentication method between the vehicle and the electronic file in the vehicle, once the vehicle fails, even if the electronic document has been copied a lot, each copy will fail with the vehicle. Invalid. Therefore, assuming that the vehicle is lost, the vehicle holder can invalidate the vehicle as long as the application for the loss, and at the same time invalidate the electronic file in the vehicle, so the electronic document is not suspected of being fraudulent.

4. In the present invention, when the vehicle is lost or damaged, the electronic document automatic security reply operation can be performed through the network. The system can automatically re-download the original electronic file combination to the newly applied vehicle. Except as otherwise provided by the electronic document verification terminal, the validity of the newly downloaded electronic document is the same as the validity of the new application. By this method, the vehicle holder can avoid the trouble of re-downloading each electronic file into the new vehicle one by one, and can automatically and safely respond quickly and conveniently.

Please refer to FIG. 1 , which is an architectural diagram of the mutual authentication system for electronic documents and vehicles of the present invention, which comprises four parts: the first part is a readable and writable vehicle 11 , which can store electronic files, and the carrier 11 includes There is a unique identification value 111; the second part is the service center 12, and the service center 12 is responsible for communicating with the vehicle 11, the vehicle authentication system 13, and the electronic document verification terminal 14, and contains the electrons stored in the vehicle. The document comparison table 121 records the electronic file list corresponding to the storage device, and when the vehicle is lost or damaged, the electronic file can be automatically returned to the new vehicle by the electronic file list. The third part is the vehicle certification system 13, It is the unique identification value of the vehicle and can verify the validity of the vehicle; the fourth part is the electronic document verification terminal 14, which is an electronic file verification end for issuing the electronic file 141, and the electronic file in the verification end of the electronic document Must be valid after being issued by the electronic document verification terminal.

Please refer to FIG. 2, which is a flow chart of the unique identification value of the vehicle for the present invention. First, the certification system verifies the identity of the vehicle holder 21, and if the identity verification is correct, the vehicle certification system will assign the identity. The carrier has a unique identification value of 22. This unique identification value cannot be changed except for the vehicle authentication system.

Please refer to FIG. 3, which is a flow chart of writing an electronic file into a carrier according to the application of the present invention. First, the service center will first verify that the applicant is indeed the holder of the vehicle 31; then the service center will verify the validity of the vehicle through the vehicle certification system 32; if the load is effective, it will be connected to To download an electronic file verification end of the electronic file, the electronic document verification end of the electronic file adds the unique identification value 33 of the vehicle to the electronic file and returns it to the service center; then the service center verifies from the electronic file Downloading the electronic file that already contains the unique identification value, and writing the electronic file to the vehicle 34; finally, the service center writes the electronic file to the action record of the vehicle to the carrier With the stored electronic file in the comparison table 35.

When the vehicle is lost or damaged, once the vehicle holder applies to the service center for the vehicle to fail, the service center will set the unique identification value of the vehicle to be invalid.

Please refer to FIG. 4, which is a flow chart of reading an electronic file according to the present invention. When the electronic file in the vehicle is to be read, three steps must be taken: reading the unique identification value 41 in the electronic file in the vehicle, verifying the validity of the unique identification value 42 if the electronic file If the unique identification value is valid, the content of the electronic file in the vehicle can be directly read; the first two steps can be completed offline, but if the electronic file needs to be verified online, proceed to step 43 to connect to the original electronic The file verification end further verifies the validity of the electronic file, and after determining the validity, reads the content of the electronic file. As can be seen from this flow, since the validity of the unique identification value must be verified before reading the electronic file, the electronic file will fail with the invalidation of the unique identification code it contains.

Please refer to FIG. 5, which is an automatic reply flow chart of the re-applying vehicle of the present invention. The present invention provides a method for automatically replying to the contents of the vehicle when the load is lost or damaged, causing the vehicle to be unusable and must be re-applied. The method of replying has two steps: applying for a new vehicle 51, allowing for new loading Containing a new unique identification value; the service center downloads the electronic file from the original vehicle into the new vehicle 52 based on the previous record, since the service center of the lost vehicle has recorded the placement in the vehicle An electronic file, so the service center can automatically transmit the unique identification value of the new vehicle to the electronic file verification end of each electronic file, so that the electronic document verification end puts the unique identification value of the new vehicle in the electronic file. And download the electronic file to the new vehicle.
