Abstract: The technique relates to a method and apparatus for dynamic destruction of data in a remote data storage platform. This involves receiving a first set of data records with random values and then updating the random values associated with the subsets of the first set of data records into actual values through one or more update operations. After sequential steps of updates, a second set of data records with actual values are obtained. After working of this data for a period of time the owner of the data again begins updating the actual values associated with the subset of the second set of data records into random values. When all the data records are updated to random values the owner of the data successfully ends the Service Level Agreement period.

Abstract: The technique relates to a system and method for correcting geometric distortions in videos and images. To correct the one or more geometric distortions in videos, the frames of the original and distorted video are mapped at the beginning and then the features associated with the mapped frames which are insensitive to geometric distortions are identified. In case of correcting geometric distortions in images, frame mapping is not required and thus the process starts from identifying the features insensitive to geometric distortions in the original image and distorted image. Then, the geometric distortion parameters are identified from the mapped features. After that, a frame level and video level average distortion of the geometric distortion parameters are determined. Finally, the geometric distortions are corrected based on the frame level and video level average distortion value.

Abstract: This technology relates to a device and method for determining co-locatability of a plurality of virtual machines on one or more physical infrastructures. The plurality of virtual machines hosts a plurality of workloads. This involves identifying workloads which have high variability from the time series data and determining the workload capacity threshold of the identified workloads. Thereafter, the candidate workloads are selected among the identified workloads to colocate on a virtual machine based on the workload variability. After that, the total capacity required by each candidate workload pair to meet the service requirement is determined based on the workload capacity threshold. Then, an optimal sharing point of each workload of the pair with respect to the other workload of the pair is identified. Further, percentage compatibility of each workload pair is determined and finally, the candidate workloads are colocated based on the optimal sharing point and percentage compatibility.
