Abstract

The invention discloses a large-scale data circulation method. The method comprises the following steps: storing ciphertext from a plurality of data sources; Receiving a decryption key encrypted by the RSA public key; Decrypting the ciphertext; Calculating the original text obtained by decryption according to a preset calculation rule; And outputting a calculation result at one or more of the datasources. The device comprises a storage unit, a receiving unit, a decryption unit, a calculation unit and an output unit. Large-scale data circulation is realized, and one side of purchase data is prevented from secondary sales. The technical problem that the data circulation efficiency is low due to the fact that only point-to-point transaction circulation can be achieved and one party purchasing data also has secondary sales is solved.

Description

technical field [0001] The present application relates to the communication field, and in particular, relates to a large-scale data circulation method and device. Background technique [0002] According to the National Development and Reform Commission's prediction, the proportion of new cars in China's intelligent networked vehicles will reach 50% in 2020, and cars will become the next important mobile terminal. [0003] In order to perceive the surrounding environmental information in real time and make appropriate responses in advance, different levels of self-driving cars are equipped with various high-precision cameras, radars and other sensors. These sensors also record a wealth of personal information while optimizing vehicle performance and service. [0004] The vehicle and owner information, as well as the trajectory generated during driving, vehicle status, maintenance and entertainment preferences, and other information are mostly owned and managed by car compani...
