A computer-implemented method for certified sensor readings from a sensor can be provided. The method includes calibrating the sensor, generating a digital certificate, signing, by the sensor, a measurement value with its private key of a public/private key pair, and sending, by the sensor, the signed measurement value such that the sensor is identifiable via its public key and the related generated digital certificate.

Sensor calibration

A computer-implemented method, a computer system, and a computer program product for managing relationships between persons and physical objects based on identifiers. A computer system configures a user device to be capable of interacting with each of a first database and a second database. The computer system verifies, by interacting with the second database, that a given object of the physical objects is a genuine object, based on a given object identifier of the given object and a digital fingerprint detected from a physical fingerprint of the given object. The computer system requests, via the first database, a transfer of a given relationship from a first person to a second person with respect to the given object, based on the given object identifier and a person identifier of the second person.

A storage system and a method for storing a data segment, a storage capacity manager and a method for managing a capacity of a storage unit, and a storage tier relocation manager and a method for relocating a data segment. The storage system includes at least two storage tiers, an access pattern evaluator, a classification unit, a selector, and logic. The storage capacitor manager includes a monitoring unit and capacity managing unit. The storage tier relocation manager includes a target storage tier, the data segment relocated to the target storage tier, and a protection measure.

Automatically organizing storage system

The present invention is notably directed to a computer-implemented method of accessing data by an application. The method comprises detecting an application that is accessing an initial file stored in a storage system; fetching an application model of the detected application, the application model comprising an association between access patterns of the detected application when accessing first files with first metadata information of the said first files; identifying one or more second files stored in the storage system, the identified one or more second files having second metadata information that are similar to the first metadata information; and prefetching the identified one or more second files.

Data prefetching for large data systems

An example operation may include one or more of receiving an export identifier to initiate an asset ownership transfer of an asset from a current owner to a new owner, identifying an asset identifier assigned to the asset and a current asset ownership session stored in a blockchain transaction, responsive to identifying the export identifier, assigning a new asset identifier to the asset, assigning a random number to an import identifier used to identify the asset transfer to the new owner, and creating a new blockchain transaction including the new asset identifier, the random number, and a new asset ownership session.

A method for storing a data segment in a storage tier of a storage unit comprising at least two storage tiers includes receiving the data segment to be stored including metadata; receiving metadata of data segments stored in the storage unit; and determining the storage tier to store the received data segment to and a protection level dependent on the metadata received and dependent on the metadata of the received data segment.

Rule-based tiered storage system

A device and method for determining number of storage devices for each of plurality of storage tiers and assignment of data to be stored in the plurality of storage tiers. The device computes an optimized number of storage devices for each tier including a classifier, which receives units as input data to be stored in the system. Based on the characteristics of the storage devices, the device outputs a data-unit-to-storage tier assignment. An optimizer receives data-unit-to-storage tier assignment from the classifier and a cost budget for the system. Thereafter, an output for the number of storage devices for each storage tier is calculated. A method for determining number of storage devices for each of a plurality of storage tiers and assignment of data to be stored in the plurality of storage tiers are also provided.

In one general embodiment, a method includes determining a sampling interval for an interpolator using at least one parameter. The method further includes applying the sampling interval to the interpolator in response to determining the sampling interval. In another general embodiment, an apparatus includes an interpolator and a controller. The controller is configured to determine a sampling interval for the interpolator using at least one parameter. The controller is also configured to apply the sampling interval to the interpolator in response to determining the sampling interval.

An apparatus includes a loop filter that receives a plurality of input signals. Each of the input signals is based on a different timing error detector output signal. The apparatus also includes a plurality of read channels, a plurality of interpolation filters, and an array of transducers. Each of the interpolation filters is in communication with a corresponding one of the read channels. Each of the transducers is in communication with a corresponding one of the read channels. The loop filter processes the plurality of input signals, and outputs a different total phase signal for each received input signal. Each of the interpolation filters samples the corresponding read channel based on one of the total phase signals output by the loop filter. The loop filter processes the plurality of input signals by calculating a phase estimate of the samples, and a skew estimate of the samples, relative to written data.
