A method, computer system, and a computer program product for image capture prevention is provided. The present invention may include, in response to embedding at least one digital security mark in a visual communication, securing the visual communication. The present invention may also include preventing, based on the embedded at least one digital security mark, an image capture of the secured visual communication.

Image capture prevention

A method, system, and computer program product for compressing an image using similar images includes: receiving a first image; storing the first image on a storage server; comparing the first image to one or more stored intra-frames (I-Frames) to determine a similar I-Frame from the one or more stored I-Frames; in response to determining the similar I-Frame, determining that one or more stored predicted frames (P-Frames) reference the similar I-Frame; comparing the first image to the one or more stored P-Frames to determine a similar P-Frame; determining whether the first image meets a P-Frame threshold level for the similar P-Frame; in response to determining that the first image meets the P-Frame threshold level, generating a first P-Frame for the first image using data from the similar P-Frame and data from the similar I-Frame to compress storage space used by the first image on the storage server.

Predictive monitoring of a rotational machine of a cooling apparatus is provided by integrating a predictive vibration analyzer into an electronics rack being cooled by the cooling apparatus. The integrating includes associating at least one sensor of the predictive vibration analyzer with the rotational machine of the cooling apparatus. The analyzer includes a predetermined harmonics table of one or more base operational frequencies and associated rotational speed harmonics for the rotational machine indicative of one or more rotational faults, and the predictive vibration analyzer automatically evaluates vibration of the rotational machine during operation of the machine by analyzing vibration data therefor, and automatically ascertains, based on the vibration data, and the predetermined harmonics table, whether the rotational machine is predicted to possess a rotational fault of the one or more rotational faults.

The present invention provides a faulty disk copy utility. A method for copying files in accordance with an embodiment of the present invention includes: obtaining a list of files to be copied from a first location to a second location; initiating copying of a file from the list; logging an identifier of the file in a log file if an error occurs during the copying; and repeating the copying and logging for each file in the list of files; wherein the copying of the files from the list does not end if an error occurs during the copying.
