In a network of intermittently-connected computers, a method and apparatus for maintaining and managing control over data objects authored, accessed, and altered by users in dynamic, distributed, and collaborative contexts. The invention method and apparatus attach to each data object an identification of a respective control policy. Each control policy comprises at least an indication of a subset of the users who may access the data object, an indication of the privileges granted to each subset of users able to access the data object, and an indication of a subset of users who may define or edit the control policy. The invention method and apparatus separate the management of the control policies of data objects from the creation and use of the data objects. The invention method and apparatus automate common policy changes, distribution of policy changes to the enforcement agents, and propagation of control policies to derivative works.

A system and method are provided for identifying discrete locations and / or sections within a pre-existing media file without modifying the media file. The discrete locations and / or sections can be associated with one or more user-selected descriptors. The system and method allows for the identifying information to be communicated to consumers of the media file and the media file to be selectively rendered by the consumer using the identifying information, thus allowing a consumer to render only the portion of the media file identified or render from a given discrete location in the media file. In an embodiment, the system and method can be performed without modifying the media file itself and thus no derivative work is created.

A system for preventing accurate disassembly of computer code. Such code masking, referred to as “obfuscation,” is useful to prevent unwanted parties from making copies of an original author's software, obtaining valuable information from the software for purposes of breaking into a program, stealing secrets, making derivative works, etc. The present invention uses assembly-language instructions so as to confuse the disassembler to produce results that are not an accurate representation of the original assembly code. In one embodiment, a method is provided where an interrupt, or software exception instruction, is used to mask several subsequent instructions. The instruction used can be any instruction that causes the disassembler to assume that one or more subsequent words, or bytes, are associated with the instruction. The method, instead, jumps directly to the bytes assumed associated with the instruction and executes those bytes for a different purpose. A preferred embodiment works with a popular Microsoft “ASM” assembler language and “DASM” disassembler. The instructions used to achieve the obfuscation include “INT” instructions. Using this approach up to 17 bytes of obfuscation can be achieved with five instructions. Each instruction remains obfuscated until executed and returns to an obfuscated state afterwards.

The present invention discloses a sharing method and device of network works, a server and a storage medium. The method comprises the following steps of: selecting original works shared on a network page; employing new works uploaded by a user, and performing derivative work on the original works to obtain shared works; and performing sharing of the shared works on the network page. In the invention, the sharing method and device of network works, the server and the storage medium form shared works through joint derivative work of the original works and the new works to enrich the resources ofthe shared works, reduce the creation difficulty of the shared works and allow more users to take part in the creation of the shared works.

A system for use on the Internet to allow automated licensing of works of authorship and access to information about licenses which have been granted. A unique work identifier is issued to each of a large number of works of authorship, most of which are available on the Internet, but some of which are not. When the works are published, whether or not on the Internet, the unique work identifier is included. The work identifier may also identify a distributor, or chain-of-distributors, through which the work has been licensed. The unique identifier leads to a web page where a user can accept an offered license to do one or more of: reproduce, distribute, perform, display, or prepare derivative works. The system then automatically generates a unique license identifier which is placed in each copy of the work prepared by the licensee. The license identifier permits tracking of further licensing.

A method, system and computer program product for evaluating an impact of a user's content utilized in a social network. Content in a document (e.g., a presentation) that has been posted on a social network environment is detected as being reused by another user in another document. The author of the reused content is then identified. A counter keeping track of the number of times this content has been adopted in derivative works is then incremented. A score (“impact score”), representing the author's ability to influence other users to adopt the author's content in other users' derivative works, is then generated based on the number of times this content has been adopted in derivative works. Social credit is then provided to the author using the impact score. In this manner, recognition is provided to the author thereby providing motivation for users to post created content in the social network.

Systems and methods provide a mechanism to protect the integrity of electronically derivative works. One aspect of the systems and methods includes receiving an original document including a first digital signature. After the document is derived, a second digital signature is created. The second digital signature may include the first digital signature, a message digest from the first digital signature, and a message digest for the second digital signature. A further aspect of the systems and methods include assigning a security key to a document processing application. The assigned key may be used to produce the second document signature.

A derivative work is encrypted using master keys generated from source data extracted from digital sources used to create the derivative work. A software application permits a mix artist to encrypt and stream a derivative work to a worldwide web server, where it is made available to consumers. A software application permits the consumers to acquire and decrypt an encrypted derivative work if the consumer has possession of a corresponding digital source for each of the digital sources used to encrypt the derivative work.

A derivative work is encrypted using a cipher created from digital sources used to create the derivative work. A software application made available for download permits a mix artist to generate a derivative-encrypted work from a derivative work that the mix artist has created using one or more of the digital sources. The derivative-encrypted work is streamed to a worldwide web server, where it is made available for download by consumers for a fee. The software application is also available for download by the consumers and permits the consumers to purchase and download any available derivative-encrypted work. However, the derivative-encrypted works can only be decrypted if the consumer has possession of a digital source for each of the source art works associated with the digital sources used to create the derivative work.

Disclosed are a method and a device for issuing rewards to performers of works based on blockchain. The blockchain network includes a plurality of business nodes, and the business nodes have the authority to publish works to the blockchain, and the virtual resources are used as the transaction medium between the multiple business nodes to conduct copyright-related transactions. For a business node that publishes deductive works, rewards are issued to the business node through the consensus mechanism in the blockchain network, so that the virtual resources corresponding to the business node increase. In addition, the virtual resource increment corresponding to the service node is determined according to the deductive level of the deductive works released by the service node.
