Description

Technical Field

[0001] The invention relates to a method for storing electronic signatures in electronic evidence, and belongs to the technical field of computers. Background Art

[0002] At present, many relevant departments are equipped with multifunctional all-in-one acquisition equipment, which has high-definition cameras, microphones, Bluetooth, Wi-Fi, 4G / 5G and other functional modules. All on-site investigation data can be completed with one device, which is connected to the evidence server via a data cable or wirelessly to perform data upload operations. A new case file will be created for each on-site investigation, and all electronic evidence will be included in the file record. The compliance and traceability of electronic evidence in the case electronic file are guaranteed by the traditional paper list plus handwritten signature. The above-mentioned handwritten signature process is very important for legal procedures. This is often the focus of arguments between the parties in court. Many cases are excluded from the list of evidence because of non-compliance in evidence collection and storage. Paper lists and handwritten signatures have a high rate of human errors due to factors such as cumbersome processes and difficulty in preservation. Summary of the invention

[0003] The purpose of the present invention is to address the defects of the above-mentioned prior art and propose an electronic signature method for electronic evidence storage. After the collection device uploads the electronic evidence to the evidence server, an electronic signature request is automatically initiated for the metadata of the case file record. The relevant personnel complete the electronic signature after completing identity authentication on the collection device with biometric recognition. The present invention uses electronic signatures to replace the paper signature process of electronic evidence file storage, improves the efficiency of case circulation, and reduces the possibility of human error.

[0004] The electronic evidence storage and electronic signature method of the present invention requires that the evidence collection device 1 has hardware modules such as network 101, biometrics 102, and secure storage area 103; the evidence server 2 has hardware modules such as network 201 and database 202.

[0005] The evidence collection device 1 of the present invention has a unique number device_id. Before executing the electronic evidence collection task, it has been bound to a relevant person (police_id) and the biometric characteristics (fingerprint or face) of the relevant person are recorded in the biometric recognition module 102 of the collection device. The private key of the relevant person is stored in the secure storage area 103 of the evidence collection device 1; the evidence server 2 only stores the identity information and public key of the relevant person, and does not store their biometric characteristics.

[0006] Method flow:

[0007] Step 1: Before the relevant personnel start the on-site investigation, they create a "case file" in the evidence collection device 1. All electronic evidence (photos, audio, video) collected by the evidence collection device 1 are stored in the file;

[0008] Step 2: After the on-site inspection is completed, the relevant institution uploads the electronic evidence in the evidence collection device 1 to the evidence server 2 through the network;

[0009] Step 3: The evidence server 2 creates a "case file" metadata record "case_metadata" in the database 202, with the "case id" number as the primary key;

[0010] Step 4: The evidence server 2 sends the case_metadata in JSON format to the evidence collection device 1 and issues an electronic signature request;

[0011] Step 5: After receiving the electronic signature request, the evidence collection device 1 sends a biometric identification request to the relevant personnel. If it passes, the private key is extracted from the secure storage area 103 and the case_metadata is electronically signed using the signature algorithm 3. The signature data is filled into the creator_signature field of case_metadata and saved as case_metadata'(4). If the biometric identification fails, the signature request is rejected;

[0012] Step 6: The evidence collection device 1 transmits case_metadata' back to the evidence server 2;

[0013] Step 7: The evidence server 2 uses the public key of the relevant person to verify the electronic signature in case_metadata'. If it passes, it is stored in the database 202, otherwise it returns an error message.

[0014] Beneficial effects:

[0015] The present invention can automatically initiate an electronic signature request for the metadata of the case file record after the collection device uploads the electronic evidence to the evidence server, and the relevant personnel complete the electronic signature after completing the identity authentication on the collection device with biometric recognition. The present invention uses electronic signatures to replace the paper signature process of electronic evidence file storage, improves the efficiency of case circulation, and reduces the possibility of human error.

[0020] The invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, the present invention provides an electronic signature method for electronic evidence storage, which automatically initiates an electronic signature request for the metadata of the case file record after the collection device uploads the electronic evidence to the evidence server, and the relevant personnel complete the electronic signature after completing the identity authentication on the collection device with biometric recognition. The present invention uses electronic signatures to replace the paper signature process of electronic evidence file storage, improves the efficiency of case circulation, and reduces the possibility of human error.

[0022] The electronic evidence storage and electronic signature method of the present invention requires that the evidence collection device 1 has hardware modules such as network 101, biometrics 102, and secure storage area 103; the evidence server 2 has hardware modules such as network 201 and database 202.

[0023] The collection device of the present invention has a unique number device_id. Before executing the electronic evidence collection task, it has been bound to a relevant person (police_id) and the biometric characteristics (fingerprint or face) of the relevant person are recorded in the biometric recognition module 102 of the collection device. The private key of the relevant person is stored in the secure storage area 103 of the evidence collection device 1; the evidence server 2 only stores the identity information and public key of the relevant person, and does not store their biometric characteristics.

[0024] Method flow:

[0025] Step 1: Before the relevant personnel start the on-site investigation, they create a "case file" in the evidence collection device 1. All electronic evidence (photos, audio, video) collected by the evidence collection device 1 are stored in the file;

[0026] Step 2: After the on-site inspection is completed, the relevant institution uploads the electronic evidence in the evidence collection device 1 to the evidence server 2 through the network;

[0027] Step 3: The evidence server 2 creates a "case file" metadata record "case_metadata" in the database 202, with the "case id" number as the primary key;

[0028] Step 4: Evidence server 2 sends case_metadata in JSON format (such as Figure 2 As shown) is sent to the evidence collection device 1, and an electronic signature request is issued;

[0029] Step 5: After receiving the electronic signature request, the evidence collection device 1 sends a biometric identification request to the relevant personnel. If it passes, the private key is extracted from the secure storage area 103 and the case_metadata is electronically signed using the signature algorithm 3. The signature data is filled into the creator_signature field of case_metadata and saved as case_metadata'(4). If the biometric identification fails, the signature request is rejected (e.g. Figure 3 shown);

[0030] Step 6: The evidence collection device 1 transmits case_metadata' back to the evidence server 2;

[0031] Step 7: The evidence server 2 uses the public key of the relevant person to verify the electronic signature in case_metadata'. If it passes, it is stored in the database 202, otherwise it returns an error message.

[0032] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
