ModernBeats Secure ID® Encryption
-Terms and Conditions-
MODERNBEATS SECURE ID® TECHNOLOGY: For the added protection and security of ModernBeats Inc and its Customers, all product files (downloaded or shipped) are encrypted with Customer ID encryption identifying the Customer's IP Address, Name, Date, and Time tied to the Customer's Order. ID Header Tags remain embedded within each file (audio or document) regardless of modification or resampling. This technology is possible due to ModernBeats developing a proprietary system where ID Tag encryption occurs at a binary root level for all audio and document files, not at traditional text header levels. Secure ID® Customer Privacy and Protection: ModernBeats Inc guarantees the full privacy and protection of its valued customers. ModernBeats Inc will never disclose valued customer information to third parties.
PERPETRATORS BEWARE: Unauthorized use, distribution, or duplication is a violation of applicable laws. With ModernBeats Secure ID® Technology, you WILL be caught and prosecuted to the fullest extent of the law. ModernBeats' attorneys have won every copyright infringement lawsuit pursued. Don't become a convict, obey the law and avoid a costly lawsuit with ModernBeats, Inc. In addition to ModernBeats, Inc's proprietary Secure ID® Tag encryption, ModernBeats Inc's attorneys use government-supported Waveform Screening Analysis Technology in a court of law to prosecute perpetrators of copyright infringement and illegally selling or distributing ModernBeats products.
