Techniques for client side multi-factor password generation include randomly removing one or more features of a record of a fingerprint image of a user and creating a distorted record of the fingerprint image by merging the record with a user input code using an encryption technique, the distorted record being reversible using the user input code. The distorted record for authentication of the user is registered.

Aspects of the invention include receiving a new problem record. A corpus of existing problem records that were previously assigned to problem record owners and grouped into documents based on their assigned problem record owners is accessed. Each document in the corpus has an assigned problem record owner. A document in the corpus that is most similar to the new problem record is identified. The identifying includes comparing text in the new problem record to text in the documents. The new problem record is assigned to the problem record owner that is assigned to the identified document.

Assigning a new problem record based on a similarity to previous problem records

A secure cloud computing environment protects the confidentiality of application code from a customer while simultaneously protecting the confidentiality of a customer's data from intentional or inadvertent leaks by the application code. This result is accomplished without the need to trust the application code and without requiring human surveillance or intervention. A client secure virtual machine (SVM) is accessible by a client who supplies commands, operand data and application data. An appliance SVM has the application code loaded therein and includes an application program interface that accesses a memory area shared by both SVMs. All access to the appliance SVM is initially revoked by an ultravisor, except for the shared memory and an encrypted persistent storage. The appliance SVM stores the application data in the persistent storage. The ultravisor manages an SVM by maintaining exclusive control over a device tree used by the operating system of the SVM.

Protecting cognitive code and client data in a public cloud via deployment of data and executables into a secure partition with persistent data

A method, computer program product, and computer system to maintain high availability of a service processor. An embodiment provides program code with a location of a second service processor (the second service processor is communicatively coupled to the first service processor). The program code stops a virtual machine during runtime, including instruction execution and IO operations, where during runtime, the virtual machine executes one or more processes to service and manage computing resources in the distributed computing environment. The program code generates a micro-checkpoint of the virtual machine. The program code resumes the instruction execution of the virtual machine and transmits the micro-checkpoint to a second service processor based on the location and then resumes IO operations. The second service processor utilizes the micro-checkpoint to enable a hypervisor on the second service processor to start a virtual machine on the second service processor.

Microcheckpointing with service processor

A system for explosively applying a fire-fighting foam is provided. The system includes a thermoelectric generator that is attached to a battery heat source. A temperature differential across the thermoelectric generator generates an electrical current having a temperature-dependent voltage. A detonator circuit is electrically connected to the thermoelectric generator. The detonator circuit measures the voltage of the electrical current. An explosive foam applicator is communicatively connected to the detonator circuit and includes a trigger mechanism that detonates a propelling charge in response to receiving a signal from the detonator circuit when the detonator circuit determines that the electrical current corresponds to temperature that is greater than or equal to a threshold temperature. The explosive foam applicator is oriented such that detonating the propelling the charge causes the explosive foam applicator to apply a foam to the battery heat source.

Embodiments of the present invention include a memory module that includes a plurality of memory devices and a memory buffer device. Each of the memory devices are characterized as one of a high random bit error rate (RBER) and a low RBER memory device. The memory buffer device includes a read data interface to receive data read from a memory address on one of the memory devices. The memory buffer device also includes common error correction logic to detect and correct error conditions in data read from both high RBER and low RBER memory devices. The common error correction logic includes a plurality of error correction units which provide different complexity levels of error correction and have different latencies. The error correction units include a first fast path error correction unit for isolating and correcting random symbol errors.

An apparatus for automatically generating a fire-fighting foam at elevated temperatures is provided. The apparatus includes a container sized to hold at least one battery. Water is stored within the container. One or more cartridges made, at least in part, of a temperature-dependent breakdown material are stored within the container. The one or more cartridges contain a foaming agent. Heat generated by a failing battery causes the temperature-dependent breakdown material to fail such that the foaming agent is released from at least one cartridge to mix with the water stored within the container.

This result is accomplished without the need to trust the application code and without requiring human surveillance or intervention. A client secure virtual machine (SVM) is accessible by a client who supplies commands, operand data and application data. An appliance SVM has the application code loaded therein and includes an application program interface that accesses a memory area shared by both SVMs. All access to the appliance SVM is initially revoked by an ultravisor, except for the shared memory. The appliance SVM processes the commands without ever saving any persistent state of the application data. The ultravisor manages an SVM by maintaining exclusive control over a device tree used by the operating system of the SVM.

Technical solutions are described for shifting wearout of an array of storage disks in a storage system. In an aspect, a method includes staggering completion of maximum number of writes for each storage disk in the array. The method also includes copying data from a storage disk in the array to a replacement disk and redirecting a request to access the data from the storage disk to the replacement disk. The method also includes, in response to passage of a predetermined duration of time since copying the data from the storage disk to the replacement disk, copying the data from the replacement disk to the storage disk and directing the request to access the data from the storage disk back to the storage disk.

Shifting wearout of storage disks

Technical solutions are described to forestall data loss caused by wearout of storage disks in an array of storage disks in a storage system by monitoring a rate of writes for a first storage disk in the array and determining a mean time to failure of the first storage disk. A start time is determined based on the mean time to failure, a number of storage disks in the array, and a time to replace a storage disk in the array. At the start time, a notification is issued as an alert to replace the first storage disk to forestall data loss caused by wearout of a second storage disk in conjunction with a wearout of the first storage disk.

An embodiment includes a method for use in operating a memory chip, the method comprising: operating the memory chip with an increased burst length relative to a standard burst length of the memory chip; and using the increased burst length to access metadata during a given operation of the memory chip.
