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 |
|---|---|
ISCC is an open standard proposal | ACRS are mostly complex services operated with proprietary software |
ISCC creates a short identifier string | ACRS do not provide a short, public identifier string |
ISCC can identify digital assets in all media formats | ACRS is not an identifier but an identification system |
ISCC is generated by a combination of multiple fingerprints and cryptographic hashing algorithms | ACRS works with large and granular fingerprints and special indexing systems |
ISCC has near duplicate content-matching capabilities (lightweight fingerprints) | ACRS is developed for content matching, can match and compare assets and small chunks in great detail |
ISCC cannot analyse content in detail | ACRS can compare assets and small chunks in great detail |
A short identifier string can be stored in databases or on blockchains very efficiently | ACRS are complex systems that requires database indexing technologies and large storage capacities |
The ISCC is optimised for the use on blockchains | It is not possible to easily store and openly provide large fingerprints |
ISCC can easily be implemented in existing applications and services | Most ACRS depend on external services and cannot easily be implemented in existing applications |
ISCC ensures interoperability of content-related processes across creators, intermediaries, retailers and other organisations, systems or repositories | Fingerprints are not interoperable |
A short identifier string allows for automated machine-to-machine communication and transactions | ACRS do not provide a short fingerprint-based identifier |
ISCC can be created by anyone with access to the content file | ACRS often requires using proprietary software and indexing/matching services |
ISCC can be used for all media content types | ACRS are often optimised for specific media types |
