Customer

Softeq's client is the global leader in flash memory storage solutions and a pioneer in Flash (NAND) technologies. It is a Fortune 500 and S&P 500 multi-divisional international organization with headquarters in the US and multiple product development branches in EMEA and Asia.

Problem

Thanks to the efforts of ardent technology innovators, bad guys are now experiencing tougher times. Now that top-tier Flash firms have integrated Write Once, Read-Many (WORM) controller technology into its flash memory cards to provide the ability to safely keep sensitive data like security camera video, court testimonies, and cash register records — for as long as 100 years — the open door for file tampering has been closed and locked.

Operating as an R&D (Research & Development) center involved in the development of state-of-the-art firmware technology for flash memory storage devices, Softeq’s team became the core contributor for implementing this groundbreaking electronic solution.

Solution

Police Protection

Japan’s police force was among the first who incorporated the new secure technology. Since some certain crimes in Japan are not subject to statute of limitations, the ability to retain evidence for many decades is a must. Japan’s law enforcement agency has integrated the “tamper-proof” cards into its forensic image archiving system to reap the following benefits:

  • Utilize tamper-proof image capture and archiving to assure the accuracy and legitimacy of forensic evidence
  • Store data files safely for up to 100 years
  • Discontinue film and use enhanced digital photography instead for evidence collection (traditionally, forensic images have been stored on 35mm film, which degrades faster compared to modern day digital media. Moreover, it is slow, inconvenient and increasingly difficult to procure)

The memory card provides easy handling: a police officer simply inserts the card into an SD WORM-compatible digital camera and captures images. Later, they can be transferred to a computer with the originals remaining intact on the WORM card.

Having conducted an extensive trial of both the SD WORM memory card's technology and its practical applications, Japan’s National Police agencies continue to deploy it across the force — to police officers, investigators, and other law enforcement personnel.

Advanced Encryption

Built on the TrustedFlash™ platform with integrated digital rights management capabilities, the WORM-enabled SD card utilizes RSA 128/256 algorithm for public-key cryptography and supports the leading advanced encryption standards such as AES 128/256, SHA 128/256, and Digital Certificate.

Results

WORM-enabled SD cards have proven invaluable for a wide array of fields where having convenient access to protected data like video, audio, confidential information, and personal data, is especially critical.

The technology has also seen a wider adoption in the commercial sectors by providers of music, games, movies, and other content who sell their products for mobile phones, laptop computers, PDAs, and other portable devices either as cards available in retail stores or as downloadable files.
