Abstract: A computer-implemented method, according to one embodiment, includes: receiving a write request which includes data, and allocating an inode entry in a central inode list, such that the inode entry corresponds to the data received. The data is allocated to a block of storage space in memory. Moreover, one or more instructions to write the data to the block of storage space are sent. A determination is also made as to whether the data fills a threshold amount of a last block of storage space. In response to determining that the data does not fill the threshold amount of the last block of storage space, one or more instructions to create an identifier at an end of the data are sent. Furthermore, one or more instructions to store a copy of the inode entry after the identifier in the last block of storage space are sent.

Abstract: Adaptive control of Input/Output (I/O) operations in a data storage system is provided to enable efficient use of the data storage system. More specifically, an interface is provided in order to adaptively control I/O operations to the data storage system. The interface receives a data request. The interface mediates with the data storage system and employs a handle which references one or more files. The handle designates how to process the data request associated with the referenced one or more files. The interface supports execution of the data request in accordance with the handle. Accordingly, the interface provides adaptive direct management of the data storage system at file granularity and/or at data request granularity as designated in the handle(s).

Abstract: Approaches presented herein enable challenge-response authentication of a user based on information captured by devices associated with the user. Specifically, in one approach, a plurality of devices associated with the user that each dynamically track and store on-device data points over a period of time are identified. A request initiated by a party claiming to be the user is received to authenticate the party as the user. An authentication question is generated in a natural language, the answer to which is a data point selected from data points on at least one device of the plurality, wherein the selected data point is discoverable by viewing data points on the at least one device. The requesting party is prompted to find the data point by presenting the authentication question to the requesting party. In the case that the requesting party returns the answer, the requesting party is authenticated as the user.

Abstract: Approaches presented herein enable challenge-response authentication of a user based on information captured by a personal internet of things (IoT) device set associated with the user. Specifically, in one approach, a personal IoT device set comprising at least one device records and stores data associated with a user. The data is synchronized and stored to a computerized authentication system, which prompts the user with an authentication question based on the synchronized and stored data. The user may find an answer to the authentication question by reviewing data recorded and stored in the device of the personal IoT device set. The user may then enter the found answer to the authentication question, thereby authenticating the user. The personal IoT device set may comprise a single device or may comprise a plurality of devices, the information of one of which may be selected as the basis of the authentication question.

Abstract: Embodiments of the present invention disclose a method, computer program product, and system for directing movements of an autonomous vehicle. A vehicle operator exiting a vehicle is detected. A plurality of metadata is received wherein the plurality of metadata includes at least location data of a user and a timestamp. A pickup time and pickup location is identified based on received metadata. A route to the pickup location is generated based on at least a default location of the autonomous vehicle. The autonomous vehicle is directed to travel to the identified location such that the autonomous vehicle is arriving at the identified pickup time. Updates to the pickup location and pickup time are determined by dynamically monitoring received metadata. A modified route is generated, in response determining updates in one or more of the pickup location and pickup time and the autonomous vehicle is redirected to the updated pickup location.

The one or more computer processors receive an access request requiring an authentication from the user, wherein the access request includes the one or more physical pressure-based inputs by the user associated with the one or more authentication parameters. The one or more computer processors determine whether the one or more authentication parameters match the user registration data. Responsive to determining that the authentication data matches the registration data, the one or more computer processors authenticate access for the user.

Abstract: An approach to de-duplicating data in an electronic text repository by performing the following steps: (i) processing one or more text documents associated with an electronic text repository to identify first instances of a plurality of words; (ii) adding words associated with the identified first instances of the plurality of words to a list, wherein each word added to the list is assigned a unique serial number; and (iii) replacing the plurality of words included in the one or more text documents with serial numbers corresponding to the words associated with the list for generating one or more reduced documents.

Abstract: A computer controls deduplication of data. The computer generates a hash of a remote data and a hash of a local data. The computer generates a set of unmatched hash data based on a comparison of the hash of the remote data against the hash of the local data. The computer generates a splitting cost that is associated with splitting the set of unmatched hash data. The computer sends a request to a server based on a comparison of the splitting cost to a threshold. The request dictates sending of the remote data to a storage controller.

Abstract: Embodiments of the present invention provides methods, computer program products, and a system for improving serial performance of a computer system storage volume. Embodiments of the present invention can be used to reduce a partition scheme of a storage volume to allow for a computer system to read the storage volume using additional system resources that were previously idle during a serial read operation. Embodiments of the present invention can be used to reserve random-access memory (RAM) to store metadata describing data stored on a storage volume that utilizes a reduced partition scheme. Once the serial read of the storage volume is complete, the embodiments of the present invention can revert the partition scheme back to the original partition scheme for normal, non-serial read operations.
