Traceability of edits to digital documents via distributed ledgers
Embodiments provide traceability of edits to a document, i.e., a verifiable and immutable provenance chain for the document. Systems and methods enable traceability of edits, by encoding, for states of the document, a fingerprint (e.g., a cryptographic hash of the document's contents) and an edit history within a block written to a distributed ledger (e.g., a blockchain). The ledger is maintained via a self-organizing peer-to-peer distributed ledger network. Once added to the ledger, the contents of a block (e.g., the document's fingerprint and edit history) are immutable and the integrity of the edit history encoded in the ledger is secure. The algorithm that generates the fingerprint is sensitive to edits of the document. The non-corruptible fingerprint encoded in the ledger is employable to detect any edits that are not included in the encoded edit history and/or inconsistent with a currently available version of the document. |

Method and control center arrangement for the control of an electrical energy transmission grid, and computer program product
An electrical energy distribution grid is controlled by a control center. Power target values for the real power and reactive power at a transfer point between the energy distribution grid and an electrical energy transport grid are prescribed by a target value device. The target values are to avoid backward feed into the energy transport grid that could lead to malfunctions. The real and reactive power target values are compared with current values at the transfer point. When a deviation of the actual values is determined, an optimization calculation is effected for the real power value and the reactive power value in the energy distribution grid to reduce or remove the deviation. The optimization generates switching commands for controllable operating devices, and a control device transmits the switching commands to the operating devices. There is also described a control center arrangement and a corresponding computer program product. |

Hosted thin-client interface in a payment authorization system
A methods and system of hosted thin-client payment authorization and authentication services for processing payments for value-added service (VAS) providers is described. A method, performed by a host server operating a thin-client device, includes receiving transaction request data at a host server computer from a thin-client device, where the transaction request data can include financial account data and biometric data. The host-server transmits a verification request message to a VAS provider and receives an indication that it is a valid merchant. The host-server transmits an authorization request message comprising the biometric data to a payment processing network (PPN), where the PPN communicates with an authentication server computer to validate the biometric data, sends the authorization request message to an issuer and receives an authorization response message from the issuer. The host-server receives the authorization response message from the PPN and sends a service fulfillment request to the VAS provider. |

Facilitating peer-to-peer transactions using virtual debit accounts of virtual wallets
The disclosure facilitates transactions between virtual debit accounts associated with corresponding transaction applications. A transaction initiation request including a transaction amount is received by a sender transaction application on a sender computing device. A recipient transaction application is detected within a proximity of the sender computing device by the sender transaction application. A virtual debit account associated with a virtual wallet of the sender transaction application is accessed and a transfer of the transaction amount is initiated from the accessed virtual debit account to a corresponding virtual debit account associated with the recipient transaction application. Upon a confirmation of the transfer being received from the recipient transaction application, a record of the transfer is provided to an issuer of the accessed virtual debit account. The use of the compatible transaction applications and associated virtual debit accounts provides fast, secure transaction capabilities between parties that may be unfamiliar with each other. |
