Systems, methods, and non-transitory computer-readable media can obtain and verify a hash chain. A hash chain can comprise at least a first data block and a second data block. The first data block can include a first portion of a stream of vehicle data. The second data block can include a second portion of the stream of vehicle data and a hash value of the first data block. Verification of whether the hash chain is authentic can be based at least in part on the hash value of the first data block.

Determining vehicle data integrity

In one embodiment, a computing device detects an identifier of an object entered by a user participating in a message session. The message session includes one or more messages including text, and the text includes the identifier. The computing device accesses an image corresponding to the object based at least in part on the identifier. The computing device provides for display to a second user the image in place of the identifier within the text.
