no. 1 example

[0066] In the first embodiment of the present invention, a data storage method is applied to data acquisition equipment, such as figure 1 As shown, the method includes the following specific steps:

[0067] Step S101, storing the collected data into a setting memory.

[0068] In this embodiment, the collected data is not specifically limited, and may be collected audio data, collected video data, or collected satellite positioning data.

[0069] For example, step S101 includes: storing the collected video data during driving into a setting memory.

[0070] For another example, step S101 includes: storing the collected video data and real-time satellite positioning data during driving into a setting memory.

[0071] In this embodiment, the memory is not specifically limited, including volatile memory (Volatile Memory), such as random access memory (Random Access Memory, RAM); it may also include non-volatile memory (Non-Volatile Memory) , such as read-only memory (Read-Only ...

no. 3 example

[0088] In the third embodiment of the present invention, a data storage method is applied to data acquisition equipment, such as image 3 As shown, the method includes the following specific steps:

[0089] Step S301, storing the collected data into a setting memory.

[0090] Step S302, according to the time stamp of data collection, the collected data is cut into a plurality of time stamp segment data; each time stamp segment data is compressed and encoded according to the hash coding rules, so as to obtain the corresponding time stamp segment data Reference tag sequence.

[0091] The collected data is compressed and encoded by the preset coding rules to obtain the reference label sequence, which effectively reduces the storage capacity of the collected data, so that the data can be transmitted for the data compressed reference label sequence, avoiding the need to modify the collected data The data transmission caused by the transmission is slow and occupies too much transm...

no. 4 example

[0095] In the fourth embodiment of the present invention, a data verification method is applied to data verification equipment, such as Figure 4 As shown, the method includes the following specific steps:

[0096] Step S401, when verifying the data stored in the setting memory by the data acquisition device, compress and encode the data stored in the memory according to a preset encoding rule to obtain reference encoded data.

[0097] In this embodiment, the memory is not specifically limited, and includes volatile memory, such as random access memory; it may also include non-volatile memory, such as read-only memory, flash memory, hard disk or solid-state hard disk; Combinations of the above types of memory may be included.

[0098] In this embodiment, the preset encoding rule is the same encoding rule as the reference encoding data generated by the data acquisition device, or an encoding rule matching the reference encoding data generated by the data acquisition device.

Abstract

The invention provides a data storage method, which is applied to data acquisition equipment and comprises the following steps of storing acquired data into a set memory; performing compressed encoding on the acquired data according to a preset encoding rule to obtain reference encoded data; and storing the reference coded data to a preset server so as to obtain the reference coded data from the preset server to verify the data stored in the set memory. In addition, the invention also discloses a data verification method, device and equipment, and a computer readable storage medium, by implementing the above scheme, integrity verification of the collected data is effectively realized, and malicious tampering of the collected data is effectively avoided; the reference coded data for data integrity verification is stored in the server, so that the defect that the reference coded data stored locally is easy to tamper is avoided, and the security of the reference coded data is effectivelyimproved.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a data storage method, a data verification method, a device, a device, and a computer-readable storage medium. Background technique [0002] With the continuous increase of automobile production and the continuous progress of technology research and development such as automatic driving, the data generated by automobile driving is becoming more and more abundant, which also puts forward higher requirements for intelligent data collection and storage of automobiles. Vehicle driving is often accompanied by various traffic accidents. The data recorded during vehicle driving will be strong evidence for accident determination, fair law enforcement and court judgment. Therefore, it is particularly important that vehicle driving data cannot be tampered with. Existing vehicle travel data acquisition records mainly use the vehicle travel recorder installed on the vehicle. Th...
