What is it? • A technical solution for an effective protection of videos covered by a copyright • Developed by INA research teams. • This innovative technology is based on a “signature”, a digital finger print which constitute a unique “genetic” code for a sequence of images. • It is not a watermarking solution. •

Why ? For Whom? • why? – TV broadcast monitoring – Content filtering on UGC (User Generated Content) sites – Filtering at end-user level – …

• who? – Rights holders –

Broadcasters

– UGC sites –

ISPs (Internet Service Providers) Jean VARRA_ INA 2008

Some technical info •

Signature is based on spatial and temporal information computed from the video (no audio) – – –

Robustness Accuracy Scalability

The signature comparison process uses a specific data structure to allow scalability.

The SDK (Software Development Kit) is available, with sample codes and usable binary files, ready to be integrated into any information system: – sig_sign – sig_index – sig_match Jean VARRA_ INA 2008

A scalable system Non-regression test: 4x24 hr TV content versus 3,000 hr reference base = zero false alarm

Currently in operation at Ina (monitoring of terrestrial broadcasts)

10 TV channels versus 200,000 excerpts = 3 PCs (3 year old) for the system core Jean VARRA_ INA 2008

An actual reference • • •

The only system in operation since 2005 for terrestrial broadcast monitoring Resulted in substantial re-invoicing for Ina Solid integration in Ina workflow and information system.

Business model and references •

Very low investment for content owners

Possibility of using a service provider to compute signatures

Software license by processor for the UGC / video sharing sites

References -

Partnership signed with Daily Motion

-

Currently under test with Internet content platforms

-

Canal+ adopted the Signature technology mid-July

-

Undergoing discussions with content owners in Europe / US

-

MPO and CJI will provide signature computation services to content owners;

-

discussions in progress with other technical service providers
