Bendik Bryde, Business Development Manager [email protected] Service provider and technology innovator within ultra-secure data storage & long-term data preservation
• Founded in 2002 by Rune Bjerkestrand • Headquarter in Norway • Reshaped the film industry with digital film printer Cinevator • Expertise in digital imaging, transferring digital information onto a trusted long term medium Long term data preservation
OAIS Reference Model Requirements for long term data preservation
Future-proof Migration-free Data retrieval process must be independent It must be migration-free to avoid the risk of data of technological obsolescence. loss, high migration cost and secure authenticity
Unalterable Permanent Secure It must be protected from cyber It must be impossible to It must be scientifically tested for attacks, logical threats, EMP and modify or delete. Offline. several hundred years longevity. physical threats.
Searchable Self-contained It must be searchable. Describe content and Metadata. metadata. Store any kind of files; digital and visual. Trusted by the EU to solve the problem € 27 million We created a digital time capsule We have digitized the film
Photosensitive optical medium where photons are used to store binary values (we write digital bits and bytes onto film) piqlFilm – nano-film with tested longevity of a minimum of 500 years piqlBox – Unique container created by a new polymer material tested to last more than 500 years
Data Binary codes Bits-on-Film Why piqlFilm is unique?
Flexible Data Storage medium: visual and digital information is stored on the same medium. Visual
Self-contained storage medium: includes all information in a human readable format to recreate the reading technology and understand the content in the future • Representation information (Metadata - Semantics, Context, SW source code, file format descriptions (JERS/SEASAT CEOS, FITS, etc) Digital Robust medium: • Open technology - Documented lifetime of 500 years • Unalterable, secure and offline medium • Integrates with the IT environment – data searchable Technology “Bits on Film”
piqlWriter: data written as high-density QR codes Encode binary data to 2D barcode (apply Forward Error Correction) Modulate light using a Digital Micromirror Device (DMD) to project the barcode on the film. piqlProcessor: photographic processing of film piqlWriter Transform the latent image into a visible and permanent image
piqlReader piqlReader: open platform for data verification and retrieval Image scanning and decoding software (open source) Data verification (checksums)
Data Frame Format
• Cross Interleaved Reed-Salomon Coding (CIRC) is applied to detect and correct a mixture of random and burst errors associated with frame defects (e.g. dust, scratches, etc.). • Data striping (frame to frame redundancy) is applied to cope with losing entire frames. Consecutive segments are stored on different physical frames). • Intelligent pixel tracking for data decoding

Access VM Why Piql is Technology Independent?
The reading process is independent of proprietary technology. Scanned Only a magnifying glass, an image capturing device and a film computer is needed
The film describes: • How to build a reader and decode the digital data • The source code of the decoding software • The documentation and description of file formats Decoding Software
