Abstract: Computer technology for combining an encryption / decryption (e/d) key with additional information to obtain a specialized e/d key. The additional information one or more of the following types of additional information: client UUID (universally unique identifier), FQDN (fully qualified domain name), database hardware information, data physical position on the hard disk and/or stored data creation date. By combining the basic key with these kind(s) of operational information and/or software / hardware identifier information, the security of the underlying encrypted data can be meaningfully enhanced.

Abstract: Methods, systems, and computer program products for operating a secure conference system. A non-limiting example of the computer-implemented method includes transmitting an invitation for a conference to a plurality of participants and instructing a blockchain system to create a blockchain network at a start of the conference. The blockchain network includes a node corresponding to each of the plurality of participants and a node corresponding to a central conference device. The method also includes obtaining, from the node of the blockchain network corresponding to the central conference device, a secret key corresponding to the central conference device and receiving an media communication stream from each of the plurality of participants.

Abstract: A method, system and computer program product for user interface action recommendations. According to the method, a target segment in a target document is determined. Correlation degree between the target segment and at least one source segment in at least one source document is determined. At least one recommended source segment is provided from the at least one source segment based on the correlation degree for a user interface action, such as copying for pasting the target segment.

Abstract: A method for automatically detecting and concealing content associated with an incoming notification in response to receiving and presenting the incoming notification on a computing device is provided. The method may include receiving the incoming notification on a computing device. The method may further include extracting and categorizing different parts of the incoming notification, and identifying features associated with each of the different parts. The method may further include classifying different parts of the content within the incoming notification based on a class coding system and identifying instructions associated with each classification. The method may further include detecting user behavior with respect to similar notifications. The method may also include automatically determining whether to conceal, partially conceal, or display on the computing device the content within the notification.

Abstract: An image depth decoder includes an NIR image buffer, a reference image ring buffer and a pattern matching engine. The NIR image buffer stores an NIR image inputted by a stream. The reference image ring buffer stores a reference image inputted by a stream. The pattern matching engine is coupled to the NIR image buffer and the reference image ring buffer, and performs a depth computation according to the NIR image and the reference image to output at least one depth value.

Abstract: A convolution operation device includes a convolution operation module, a memory, a scale control module and a scaling unit. The convolution operation module outputs a plurality of convolution operation results containing fractional parts. The memory is coupled to the convolution operation module for receiving and storing the convolution operation results containing the fractional parts, and outputs a plurality of convolution operation input values containing fractional parts. The scale control module is coupled to the convolution operation module and generates a scaling signal according to a total scale of the convolution operation results containing the fractional parts.

Abstract: A method, a computer program product, and a computer system for conditional permission control in a digital data sheet based on permission formulas. A computer checks permission formulas of data cells in the data sheet, in response that a user opens the data sheet. The computer sets cell permissions for the data cells based on the permission formulas. The computer rechecks the cell permissions, in response to that the user edits one or more of the data cells. The computer resets the cell permissions based on the permission formulas.

Abstract: A computer-implemented method includes identifying a document that is operated upon by a real-time collaborative editing system. The document includes a first active region and additional active regions. The method identifies a first node and one or more additional nodes, all accessing the document via the real-time collaborative editing system. The method identifies a second node that is one of the one or more additional nodes. The method identifies a second active region, which is one of the additional active regions. The method identifies a first node view, which displays the first active region via the first node. The method identifies a second node view. The second node view displays the second active region via the second node. The method responds to input from the first node by creating a third node view that is displayed via the second active region and presented via the first node.
