  • Publication number: 20230281583
    Abstract: Systems and techniques for enabling the automation of blockchain processes within an NFT platform, through structures and techniques for generating and maintaining descriptors of content and users, are illustrated. One embodiment includes a method for selecting personalized token-directed actions. The method determines a tag including metadata associated with a token. The method determines a profile associated with a user, wherein the user is at least one of an owner of the token and a content creator associated with the token. The method performs a clustering based at least one of the tag and the profile, wherein the clustering includes a collection of tokens sorted according to at least one of shared categories of tokens and shared categories of token users. The method identifies an action corresponding to the token, based on the clustering, wherein the action governs future token access by the user. The method initiates the action.

  • Publication number: 20230100422
    Abstract: Systems and techniques to facilitate transaction management in NFT-directed environments within an NFT platform are illustrated. One embodiment embeds an anchor into an application for utilizing tokens, wherein the anchor includes a verifier and an identifier unique to the application. The method verifies, using the verifier of the anchor, that a token is compatible with the application. The method imports the token into the application. The method associates the anchor with a lock, wherein the lock governs access to content of the token. The method identifies a completed transaction that changes access rights associated with the token, wherein the transaction is identified using at least one of information included in the anchor and information included in the lock. The method transmits, to a party to the transaction, a lock value, wherein the lock value, when detected by the lock, allows the party to access the token.

  • Publication number: 20230006976
    Abstract: Systems and methods for providing security in distributed and tokenized environments in accordance with various embodiments of the invention are described. A method for bridging between blockchains, includes: bridging an entry from a first blockchain to a second blockchain, where the entry is associated with an event; determining a classification of the entry, where the classification is one of confirmed, delayed, and blocked; performing an action based on the classification of the entry; where the action includes at least one action selected from a group including: determining the classification is confirmed and recording (130) on the second blockchain the entry and removing the entry from several entries, determining the classification is blocked and removing the entry from the several entries, and determining the classification is delayed and keeping the entry for an additional time period.

  • Publication number: 20220391887
    Abstract: Systems and devices to account for automated conditional payments from within an NFT platform to maintain resources including (but not limited to) computer systems and/or sources of data relied upon by the platform are disclosed. One embodiment is a system that includes a paying module and a bounty hunting module. The paying module generates an agreement, the agreement including terms of the performance of service. The bounty hunting module performs steps for ensuring the service is performed. The bounty hunting module obtains publicly verifiable evidence related to the performance of service. The bounty hunting module generates an assertion including the publicly verifiable evidence and a reference to a public key. The bounty hunting module posts the assertion to an immutable ledger entry. The bounty hunting module obtains payment based on validity of the assertion, wherein the assertion is valid when the assertion is determined to be true.

  • Publication number: 20130246800
    Abstract: System and method for securing sensor data in a computer system that includes a host processor and memory that stores an operating system, and an embedded controller coupled to the host processor. The embedded processor receives sensor data for a user from at least one sensor, and encrypts and/or digitally signs the sensor data, thereby generating protected sensor data, or performs pattern recognition on the sensor data, thereby generating user identification data. The embedded processor then sends the protected sensor data or the user identification data to the operating system or another process coupled to the computer system. The protected sensor data or the user identification data are used for secure transmission of the sensor data.

  • Publication number: 20120331303
    Abstract: A method and system for preventing execution of malware in a computing device. The method includes loading code into a non-executable memory of the computing device and validating an authentication signature associated with the code. Subsequently, the code is decrypted and finally, the decrypted code is executed in an executable memory upon a determination that the authentication signature is valid.

  • Patent number: 7849253
    Abstract: In one embodiment, the invention comprises a flash-media controller used for writing new data from an external system to a local flash-memory device. The newly written data may replace old data previously written to the flash-memory device, and may be written directly to unused locations within the flash-memory device. The flash-media controller may comprise a table of block descriptors and sector descriptors used to track specified characteristics of each block and sector of the flash-memory device, thereby allowing for write sequences to non-contiguous sectors within a block. Accordingly, copy operations may be deferred under the expectation that they will eventually become unnecessary, thereby designating old data as having become stale.

  • Patent number: 7310498
    Abstract: A system and method for maintaining communications with a radio frequency (RF) peripheral device such as an RF input device and an RF output device. A computer may search for an RF peripheral device by transmitting a signal request on available channels until a response is received from an RF peripheral device. If the RF channel becomes busy and/or jammed, the RF peripheral device may tune into a predetermined channel while the computer scans for another channel to use. Once the computer finds a better channel, the computer may go to the predetermined channel and broadcast the new channel location to the RF peripheral device. In addition, if an RF signal arrives incomplete or corrupt, the computer may transmit a negative acknowledgement to the RF peripheral device, which may retransmit the previous RF signal.
