Claims (4)

1. A method of tamper-resistant contract data acquisition and generation, the method comprising:
the lower business department collects heterogeneous contract data based on a preset data collection tool, carries out data cleaning and conversion processing on the heterogeneous contract data to generate contract data with preset rules, encrypts the contract data with the preset rules based on an RSA asymmetric encryption algorithm to generate a contract encryption data packet, and sends the contract encryption data packet to the upper business department;
after receiving the contract encryption data packet sent by the lower-level business department, the upper-level business department decrypts the contract encryption data packet based on the preset data acquisition tool to obtain contract data of a preset rule, and the contract data comprehensive decision is completed based on the contract data of the preset rule;
the method further comprises the steps of:
the lower business department collects structured, semi-structured and unstructured data with different timeliness through a preset data collection tool and a preset data access method based on a stream processing technology to generate heterogeneous contract data;
the method further comprises the steps of:
based on preset rules, metadata and architecture, carrying out data cleaning and conversion processing on the heterogeneous contract data to generate contract data of the preset rules;
the method further comprises the steps of:
adding the data packet of contract data with preset rules into a cache to obtain a contract data packet encryption sequence;
determining an encryption data packet of an RSA asymmetric encryption algorithm corresponding to contract data of the preset rule based on attribute information of the contract data of the preset rule;
encrypting the contract data of the preset rule based on an RSA asymmetric encryption algorithm to generate a contract encryption data packet;
the method further comprises the steps of:
performing visual operation on the contract encryption data packet in the preset data acquisition tool to generate and export a contract encryption data packet in a preset format;
transmitting the contract encryption data packet to a superior business department;
the method further comprises the steps of:
after receiving the contract encryption data packet sent by the lower-level business department, the upper-level business department decrypts the contract encryption data packet based on the preset data acquisition tool;
if decryption fails, generating alarm prompt information that the file is tampered;
the method further comprises the steps of:
and after the superior business department obtains the contract data of the preset rule, cleaning, converting and warehousing the contract data of the preset rule.
2. A tamper-resistant contract data acquisition and generation apparatus implementing the method of claim 1, the apparatus comprising:
the lower-level data processing module is used for acquiring heterogeneous contract data based on a preset data acquisition tool, carrying out data cleaning and conversion processing on the heterogeneous contract data to generate contract data of preset rules, encrypting the contract data of the preset rules based on an RSA asymmetric encryption algorithm to generate a contract encryption data packet, and sending the contract encryption data packet to an upper-level business department;
and the upper-level data carding module is used for decrypting the contract encryption data packet based on the preset data acquisition tool after receiving the contract encryption data packet sent by the lower-level business department to obtain contract data of a preset rule, and completing contract data comprehensive decision based on the contract data of the preset rule.
3. An electronic device comprising a processor and a memory having stored thereon computer readable instructions that when executed by the processor implement the method of claim 1.
4. A computer readable storage medium, having stored thereon a computer program which, when executed by a processor, implements the method of claim 1.
