Unlocking digital content embodied in digital readable form on a digital media carrier includes generating a test based on text that is printed in a physical copy of the digital content, prompting a user to input text that appears on a specific page of the physical copy, evaluating whether the user entered the correct word; and if the word was correct, unlocking the digital content.

In some implementations, a computing device may obtain an original digital media asset published to a server device along with a distributed ledger that tracks ownership of the original digital media asset. The computing device may generate a customized digital media asset that replaces the original digital media asset, and modify the distributed ledger to indicate the customization or modification of the original digital media asset and identify the customized digital media asset and the ownership thereof. The computing device may publish the customized digital media asset to a server device for distribution. Upon transfer of ownership of the customized digital media asset to a new owner, the distributed ledger may be modified to indicate the new ownership of the customized digital media asset.

A user selection of one or more of a plurality of content is received. The selected content is encrypted by a first encryption key that is remote and unknown to the distribution server. Payment information associated with the user selection is also received and verified. The selected content from is retrieved from a remote database. The first encryption key corresponding to the selected content to decrypt the encrypted content corresponding to the user selection is obtained. Decryption is performed by a hardware-based engine of the distribution server that is isolated from a host processor of the distribution server. The content corresponding to the user selection is encrypted according to a second encryption key that is known to the distribution server.

The present invention discloses a verifiable lockbox registry for copyrightable work which insures verifiable and non-tamper date of creation for a work.

A method for integrating a Proof of Storage (PoS) into a blockchain increases security, robustness and verifiability of a blockchain network. A part of the blockchain to be stored is received at a first one of a plurality of mining nodes of the blockchain network. The part of the blockchain is stored. Mining of the new block is bound to the stored data and performed so as to enforce that the mining nodes store different parts of the blockchain. The PoS is integrated into the new block. The PoS is verified before accepting the new block into the blockchain.

A non-transitory computer-readable recording medium stores an NFT uniqueness ensuring program causing a computer to perform a process of: storing information associated with a non-fungible token (NFT) already issued on a blockchain as existing NFT associated data in a memory; performing a first determination process of comparing data content of NFT associated data of a new NFT to be issued with data content of the existing NFT associated data at a time of issuance of the new NFT; and determining presence or absence of duplication between the NFT associated data of the new NFT and the existing NFT associated data.

A system and method for operating a cryptocurrency, including generating, by first computing devices, raw data sets representative of activities performed by respective users while each of the users is using the Internet. A second computing device may determine an aggregate data value of at least a portion of an aggregate of the raw data sets. The at least a portion of the aggregate of the raw data sets being received from the users who contribute that portion of the raw data sets, the contributing users being data contributors. A basis value of a cryptocurrency as a function of the aggregate data value may be established. Total quantity of the cryptocurrency in circulation may be regulated as a function of the aggregate data value.

A user selection of one or more of a plurality of content is received. The selected content is encrypted by a first encryption key that is remote and unknown to the distribution server. Payment information associated with the user selection is also received and verified. The selected content from is retrieved from a remote database. The first encryption key corresponding to the selected content to decrypt the encrypted content corresponding to the user selection is obtained. Decryption is performed by a hardware-based engine of the distribution server that is isolated from a host processor of the distribution server. The content corresponding to the user selection is encrypted according to a second encryption key that is known to the distribution server.

Computer-implemented methods and systems are provided digital content data over a network. In accordance with one implementation, a method is provided that includes: generating, in response to a download request for digital content data, a download address for the digital content data, and transmitting the download address to a client; authenticating, at a content server, the download request; downloading, over the network to the client, the digital content data after the download address is authenticated; receiving, from the client, a request for a license to access and playback the downloaded digital content data; authenticating, at an application server, the license request; and providing, to the client device, the license for the digital content data after the license request is authenticated, the license enabling the client device to access and playback the digital content data.
