Liccium app

What can I do with Liccium?

Rightsholders

Everyone can create, manage and register content-derived, decentralised identifiers on blockchain networks. Rightsholders can declare and digitally sign metadata and rights management information and inseparably connect them to digital content.

Verifiers

Everyone can identify digital media content and get access to trustworthy metadata and rights management information. Credentials allow to verify registrations, declarations, public keys and identities.

Online platforms (OCSSP)

Online platforms (OCSSP) can use Liccium to generate ISCC CODES– decentrally, on their premise! This way they can unambiguously identify digital content (UGC) without access to any metadata and verify the authenticity of the original content.

This is rather abstract ...

Ok, the process starts with your content on your local device or cloud storage. You can select a digital media file, and in seconds Liccium will extract a unique ID from it: the ISCC.

The ISCC is derived from the digital media asset itself, there is no need to manually select and apply an identifier to the content. From now on it will represent your content in any transaction as a persistent reference of your digital asset.

As a second step you can declare the ISCC on a public ledger. Your digital signature transparently connects your pseudonymous identity to the ISCC that represents your content. Nothing more and nothing less.

As a consequence of this declaration, you will receive a unique declaration ID. The ISCC-ID is owned by you, globally unique and resolvable. This registration ID retains a record of the registration transaction, connecting you (respectively your pseudonymous identity) to the content.

The ISCC-ID is important. Because from now on you can use it to attach information to the content: metadata, ownership information, licensing or rights management information, reviews etc., whatever seems relevant for you to associate with the content  – and this data will always and unambiguously be associated with your content and your pseudonymous identity.

What is required to register content with Liccium?

To register content on a public blockchain you need a wallet. Liccium will allow to declare ISCC codes on various blockchains. In order to perform transactions on Ethereum, Polygon and other EVM-based blockchains, you need to have a MetaMask wallet and create an address for each network.

In general, creating a MetaMask address is super useful, relatively easy and well documented. You can find further information on https://metamask.io/ and a lot of answered questions on their FAQ list: https://metamask.io/faqs.html

For the transactions you need the tokens of the selected blockchain network in order to pay for gas or transaction fees.

Did someone mention the word 'blockchain'?

Liccium will support Ethereum, Polygon, and in the future Tezos, NEAR, Solana, etc.

Pricing

And there are no costs involved in using Liccium?

For rightsholder declating content and individual verifiers, the services of the Liccium app are designed to be free of charge.

You mentioned tokens, though?

Transactions on public blockchain networks usually cost gas or transaction fees. Please keep it in mind that this depends on the selected network you want to use for your declarations.

Privacy

No registration, no login ... Seriously?

Liccium is a decentralised application. The services of the Liccium app require no registration or login. This means that no user credentials, no personal user data, no email addresses or passwords are stored on Liccium servers. Awesome, isn’t it?

Some services, like the declaration of ISCC codes (write operations) require a wallet, that contain the user’s key material and the derived blockchain address. Only you will have access to your private key. No user data is stored on our servers.

Content Handling

What happens with my digital assets?

To generate the ISCC codes from the content, digital assets have to be temporarily uploaded to the service.

The upload is encrypted in transport via https. After generation of an ISCC, the digital asset will be permanently deleted from the servers. In general, no content will be permanently stored on Liccium servers!

If you have terrabytes of assets and/or do not want to generate content codes via the service, you might be interested in using the Liccium VM. With the Liccium VM, the Liccium app will run on a virtual machine on a server that is controlled by yourself. Thec virtual machine can be installed in your local network or on the servers of your data centers. This allows you to manage your digital media assets on premise and to generate ISCC without the need to upload content to the service.

Feel free to reach out to install the Licium VM.

ISCC

What is the ISCC?

The International Standard Content Code (ISCC) is a proposal for a new open and decentralized identifier for digital media assets from all media sectors and of all media types, like text, image, audio and video.

The open specification and open source development are maintained by the not-for-profit ISCC Foundation. This will ensure interoperability and transparency of decentralised digital content identification.

The main distinguishing feature of the ISCC – in comparison to existing content identifiers – is the fact that the ISCC is derived from the digital media assets itself. This means that an ISCC can be generated by anyone with access to the content, free of charge by using open-source software.

The ISCC has been accepted as ISO/AWI 24138 International Standard Content Code (ISCC), as part of ISO/TC 46/SC 9: https://www.iso.org/standard/77899.html
