New pending patent applications are published on Thursdays by the USPTO. Both of today's Spotlight Applications concern aspects of digital watermarking. Assigned to Fortinet, the first of today's applications discloses techniques for data leak protection based in part on watermarking. Assigned to Toshiba, the second patent discloses techniques for digital watermark embedding.
20160099942, "Data leak protection," assigned to Fortinet.
Abstract
Methods and systems for Data Leak Prevention (DLP) in an enterprise network are provided. According to one embodiment, a data leak protection method is provided. Information regarding a watermark filtering rule is received by a network security device. The information includes a sensitivity level and an action to be applied to files observed by the network security device that match the watermark filtering rule. A file attempted to be passed through the network security device is received by the network security device. A watermark embedded within the received file is detected by the network security device. A sensitivity level associated with the watermark is compared by the network security device to the sensitivity level of the watermark. When the comparison results in a match, then the action specified by the watermark filtering rule is performed by the network security device.20160099003, "Digital watermark embedding device, digital watermark embedding method, and computer-readable recording medium," assigned to Toshiba (JP).
Abstract
A digital watermark embedding device includes a synthesized voice generating unit that outputs a synthesized voice according to an input text and outputs phoneme-based alignment regarding phonemes included in the synthesized voice; an estimating unit that estimates whether or not a potentially risky expression is included in the input text, and outputs a potentially risky segment in which the potentially risky expression is estimated to be included; an embedding control unit that associates the potentially risky segment with the phoneme-based alignment, and decides and outputs an embedding time for embedding a watermark in the synthesized voice; and an embedding unit that embeds a digital watermark in the synthesized voice at a time specified as the embedding time for the synthesized voice.
