Selective deposition method to form air gaps

A method for depositing a film to form an air gap within a semiconductor device is disclosed. An exemplary method comprises pulsing a metal halide precursor onto the substrate and pulsing an oxygen precursor onto a selective deposition surface. The method can be used to form an air gap to, for example, reduce a parasitic resistance of the semiconductor device.

System and methods for automated detection, reasoning and recommendations for resilient cyber systems

A method for securing an IT (information technology) system using a set of methods for knowledge extraction, event detection, risk estimation and explanation for ranking cyber-alerts which includes a method to explain the relationship (or an attack pathway) from an entity (user or host) and an event context to another entity (a high-value resource) and an event context (attack or service failure).

Pre-Operative Registration of Anatomical Images with a Position-Tracking System Using Ultrasound

A method includes receiving multiple measurements, acquired using a registration tool including an ultrasound (US) transducer and a position sensor of a position-tracking system. The measurements are acquired by attaching the tool to multiple locations on a patient head and acquiring position measurements of the position sensor and respective US measurements of bone tissue at the locations. First positions of the bone tissue are calculated based on the position measurement and the US measurements obtained using the registration tool. Second positions of the bone tissue are identified in an anatomical image of the patient head. The anatomical image is registered with a coordinate system of the position tracking system, by correlating the first positions and the second positions, to enable tracking a medical instrument, which is inserted into the patient head and includes another position sensor of the position-tracking system, using the anatomical image registered with the position-tracking system.

Checkout and payment

A key ceremony application creates bundles for custodians encrypted with their passphrases. Each bundle includes master key share. The master key shares are combined to store an operational master key. The operational master key is used for private key encryption during a checkout process. The operational private key is used for private key decryption for transaction signing in a payment process. The bundles further include TLS keys for authenticated requests to create an API key for a web application to communicate with a service and to unfreeze the system after it has been frozen by an administrator.

Detection of computerized bots and automated cyber-attack modules

Devices, systems, and methods of detecting whether an electronic device or computerized device or computer, is being controlled by a legitimate human user, or by an automated cyber-attack unit or malware or automatic script. The system monitors interactions performed via one or more input units of the electronic device. The system searches for abnormal input-user interactions; or for an abnormal discrepancy between: the input-unit gestures that were actually registered by the input unit, and the content that the electronic device reports as allegedly entered via such input units. A discrepancy or abnormality indicates that more-possibly, or necessarily or certainly, a malware or automated script is controlling the electronic device, rather than a legitimate human user. Optionally, an input-output aberration or interference is injected, in order to check for manual corrective actions that only a human user, and not an automated script, is able to perform.

Facilitating direct rider driver pairing for mass egress areas

A mobile computing device can store a rider application for an on-demand transportation service. Based on the mobile computing device being in a mass egress area, the rider application can initiate a late-binding state to enable a direct pairing between the user and an available driver. In the late-binding state, the mobile computing device can receive a unique match code from a backend transport system that manages the on-demand transportation service, and display the unique match code on the display screen to facilitate the direct pairing.

User account management via a distributed ledger

User access to a set of data stored in a distributed ledger, wherein the distributed ledger is stored by a plurality of node computing entities, is provided. A first node computing entity receives a share key request indicating that a first user account has authorized a second user account to have access to a set of data stored in the distributed ledger. A data access key (DAK) for accessing the set of data is encrypted using an encrypting key of the second user account. A block comprising the encrypted DAK is generated, signed using a signing key of the first user account, and posted to the distributed ledger. The block is authenticated using an authentication key of the first user account and accessed via a decrypting key of the second user account such that the second user account may use the DAK to access the set of data.

Storage device storing data using raid

A storage device includes a plurality of first memories, a controller, and a second memory. The controller controls the first memories such that first and second data chunks associated with target data are distributively stored in the plurality of first memories. The controller generates a first intermediate parity using the first data chunk, which is processed immediately before the second data chunk. When the second data chunk is not a data chunk which is processed last in connection with the target data and the first intermediate parity is buffered in the second memory, the controller generates a second intermediate parity using the first intermediate parity buffered in the second memory and the second data chunk, and outputs the second intermediate parity to the second memory to be buffered.

Data storage device and data writing method thereof

A data storage device including a flash memory and a controller is provided. The flash memory has a plurality of TLC blocks, each of which includes a plurality of pages. The controller checks whether any of the TLC blocks was undergoing a write operation and unfinished at the time that the power-off event occurred when the data storage device resumes operation after a power-off event. When a first TLC block was undergoing the write operation and unfinished at the time that the power-off event occurred, the controller further checks whether data stored in a page which was the last one being written in the first TLC block can be successfully read, and continues to write the remaining data into the first TLC block when the data of the page which was the last one being written in the first TLC block can be successfully read.

Replication of data objects from a source server to a target server

Data objects are replicated from a source storage managed by a source server to a target storage managed by a target server. A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.
