Abstract: Aspects of the disclosure relate to multicomputer processing and dissemination of data files. A computing platform having at least one processor, a memory, and a communication interface may search one or more social media platforms for unauthorized dissemination of a data file. The computing platform may correlate a unique identifying feature(s) of the disseminated data file to that of a copy of the data file previously distributed to a linked user account. The computing platform may transmit, via the communication interface, to an administrative computing device, an unauthorized dissemination report which, when processed by the administrative computing device causes a notification to be displayed on the administrative computing device. The notification may identify the linked user account associated with the unauthorized dissemination, the name, content, or general nature of the data file, and/or the social media platform(s) on which the data file was discovered.

Abstract: Aspects described herein relate to a computer system preventing embedded data from being surreptitiously transmitted in attached image files of e-mail messages, where the embedded data is inserted using steganography. The computer system may include a Simple Mail Transfer Protocol (SMTP) e-mail server that transforms an attached image file and replaces the original attached image file with the transformed image file. If the attached image file comprises a stego-image file (where data is embedded in the image), a recipient of the e-mail is unable to extract the embedded data because the recipient does not know a centrally managed key. In addition, the computer system may store images that a user sends as attached files in e-mail messages over a predetermined time duration. If the user sends an e-mail message having an attached image that matches previously sent stored images, an alarm may be generated indicating a potential steganography e-mail event.

Abstract: The invention provides a method for creating or refining a mathematical correction model for correcting dynamic measurement errors in a co-ordinate measurement machine having at least 3 linear machine axes X, Y, and Z, each comprising a machine linear scale, and provided with a measurement probe. An error model for considering acceleration errors is created and refined using actual measurements of the probe position when accelerating. Also the probe offset from the linear translation axes is considered.

Abstract: A guideway 10 of a guideway set in a coordinate measuring machine has a scale in the form of a metal strip clamped and bonded to an accessible face 46 of a spar 30, the latter being formed of a thermally stable material and being connected at one end to a reference position defined by a bracket 18 and a mounting plate 16 on the guideway 10. The spar 30 is mounted on the guideway 10 by spaced blocks 34 which are designed to accommodate any longitudinal movement of the guideway 10 due to thermal expansion, so that the spar 30 and the scale are effectively maintained in position. Because relative movement between the spar 30 and the scale is substantially prevented, the position of the scale is substantially fixed, providing improved scale accuracy.

Abstract: A vertically-movable carriage 18 has an attached first electric motor 22 which, through rollers 24, provides a friction drive with a traction bar 16. The carriage 18 is connected by a wire rope 26 to a counterbalance weight 32. The weight (32) has an attached second electric motor 36 which, through rollers 38, provides a second friction drive with a guide bar 34. The total mass of the motor arrangement is thereby split, with one motor compensating for the other.
