Abstract: Techniques for managing electronic user profiles are presented herein. An example method includes accessing, from a data structure, a user profile. The user profile can include a profile identifier and a plurality of data fields. The method also includes displaying, on a display device, an interactive user interface. The user interface can include a plurality of user interface action elements. Each of the user interface action elements can be associated with a data field in the data structure. Each of the user interface action elements can also be individually selectable by a respective user action to transmit the associated data field to a remote device. In response to receiving a selection of a user interface action element, the method can further include transmitting the associated data field and the profile identifier to a router configured to send, based on the profile identifier, the associated data field to the remote device.

Abstract: Techniques are shown for key management using a traceable key block-chain ledger involving creating a cryptographic key at a key source, generating a key block on a block-chain ledger corresponding to the cryptographic key, and securely modifying the key block to include metadata describing the key source. The techniques also involve performing a first key transaction with the cryptographic key, generating a first transaction block on the block-chain ledger corresponding to the first key transaction with the cryptographic key, linking the first transaction block to the key block and securely modifying the first transaction block to include metadata describing the first key transaction with the cryptographic key.

Abstract: A cryptographic tracking engine is disclosed that can track a user's data over the Internet in a way that allows the user to maintain control over the data downstream while maintaining the security of the stored data. An online entity provides an identifier that is encrypted using a first mechanism. Further, the user provides a data item for an electronic communication between two users. The data item is encrypted using the first mechanism. The data encrypted using the first mechanism is stored in a cryptographic entry. Other data for the electronic communication between the a first and second user is encrypted using a second encryption mechanism, such as a block cipher. The user can then selectively expose data stored in the cryptographic entry on a block-by-block basis to track exchanges of data over the Internet.

Abstract: Techniques are shown for key management using a traceable key blockchain. A first block corresponding to a cryptographic key is generated on the blockchain, and the first block is securely modified to include metadata describing a key source for the cryptographic key. A second block corresponding to a first key transaction with the cryptographic key is generated on the blockchain, the second block is linked to the first block, and the second block is securely modified to include metadata describing the first key transaction with the cryptographic key.

Abstract: Techniques are shown for key management using a traceable key block-chain ledger involving creating a cryptographic key at a key source, generating a genesis block for a key block-chain ledger corresponding to the cryptographic key, and securely modifying the genesis block to include metadata describing the key source. The techniques also involve performing a first key transaction with the cryptographic key, generating a first transaction block corresponding to the first key transaction with the cryptographic key and adding the first transaction block to the key block-chain ledger, and securely modifying the first transaction block to include metadata describing the first key transaction with the cryptographic key.

Abstract: Techniques are shown for key tracing using a traceable key block-chain ledger involving, in response to detection of an attack on a resource protected by a cryptographic key, retrieving a key block-chain ledger corresponding to the cryptographic key having one or more transaction blocks. Each transaction block corresponds to a key transaction with the cryptographic key and includes metadata describing the key transaction with the cryptographic key. Metadata from the transaction blocks in the key block-chain ledger is used to trace the key transactions of the cryptographic key to a point of attack. A transaction block corresponding to the point of attack is determined and an alert is generated indicating the point of attack with metadata from the transaction block corresponding to the point of attack.
