What is the difference between ISCC and ACR software?

The ISCC makes use of technologies related to ACR (automatic content recognition technologies) to come up with a new short and generic standard identifier for digital content – but ISCC is not an ACR. The following table provides a comparison between the ISCC system and ACR technology.

ISCC	ACR
An open identifier standard proposal	Based on proprietary software
Creates a short identifier string, generated by a combination of multiple fingerprints and cryptographic hashing algorithms	Not an identifier but a content identification system, working with large and granular fingerprints and special indexing systems
Can be generated by anyone with access to content for all media types and formats	Often optimised for specific media types
Has near duplicate content-matching capabilities (lightweight fingerprints)	Developed for content matching, can analyse and compare assets and small chunks in great detail
Can be easily implemented in existing applications, which ensures interoperability across entities	Detailed fingerprints not interoperable
