150150## **How does Scribd protect intellectual property?**
151151
152152Scribd is fully compliant with the DMCA and complies with all applicable laws. Scribd responds to valid notifications of copyright infringement within 2 business days. Scribd has also developed BookID, an automated copyright protection system that helps to safeguard intellectual property on Scribd.com and in the Scribd mobile app. BookID scans every document uploaded to Scribd and removes those that have the same, or a substantially similar, fingerprint. BookID intermittently scans the entire Scribd library to remove matching content that was uploaded prior to fingerprinting. BookID's approach reduces misidentifications and enables the detection of infringing works even if they have been altered to some degree.

162158## **How does BookID work?**
163159
164160BookID algorithmically analyzes computer-readable text for semantic data that it then encodes into a digital "fingerprint." BookID stores the fingerprints of known copyrighted works on a secure server that is inaccessible to the Internet and the general public.

180172## **Is BookID guaranteed to detect all copyright infringements?**
181173
182174No. BookID relies on computer-readable text, which is not necessarily the same as text that is readable by humans. Content scanned from paper sources may not contain computer-readable text, which makes those sources unsuitable for fingerprinting. Similarly, text that is encoded with optical character recognition (OCR) technology may contain garbled or partial data. These conditions make it very difficult, if not impossible, to detect matches.
183175
184176BookID's fingerprint scanner cannot detect specific keywords, titles, names, copyright notices, or other disclaimers that are part of a document's text. In other words, BookID cannot be programmed to block all documents that contain a book's title. Likewise, BookID cannot translate different languages. If BookID fingerprints an English-language document, it can only detect subsequent uploads that are also in English.
