Long-Term Digital Preservation

Abstract/Technology Overview

Piql safeguards your irreplaceable information!

Piql solves the problem of storage medium- and technology-obsolescence, and guarantees that data can be retrieved in the near and distant future.

Piql is migration-free and self-contained.

Piql has developed an ultra-secure data storage and long-term digital preservation solution, the Piql System. Piql has converted a photosensitive film into a self-contained digital preservation medium, the piqlFilm. The piqlFilm is kept in the piqlBox, and has a longevity of 500+ years, – with guaranteed read-back of data in the future.

It can store both visual information and digital data simultaneously. No other storage medium has this capability. Being an offline and true WORM solution, data cannot be hacked, manipulated or deleted.

The solution fully integrates with a standard IT environment and will be offered as a managed service, Piql Services, through a global network of Piql Partners. These Partners will use the Piql System, that constitutes the piqlWriter (to write data onto the film) and the piqlReader (to read data off the film) to provide Services to clients.

Many industries and government institutions have commercial, legal or social responsibilities to keep data available for longer periods, even into "eternity".

Piql's long-term digital preservation services are intended for data that needs to be kept authentic and with a guaranteed availability even after 25, 50, 100 or even 500 years.

Potential Applications

Piql has clients in different types of industries, and has focused on the following six segments where Piql's unique features makes a real difference:


Public Administration & Archives:

Ex: The National Archive of Mexico decided to put pieces of the most valuable information they have on piqlFilm and even store it in the Arctic World Archive.


Culture & Memory Institutions:

Ex: National Museum of Norway gained interest in Piql’s migration-free solution as they were looking to develop a complete new workflow of access and preservation of their digital assets.


Audio-Visual and Media:

Ex: Czech Radio, the public radio broadcaster of the Czech Republic, has a large audio archive representing global and Czech historical events.


Industry & Manufacturing:

Ex: Navantia, a large shipbuilding yard in Spain that assembles ships with a lifetime of up to 60 years. The company is required to keep all documentation and information about all parts of the ship for more than the expected lifetime of the vessels.


Defence, Justice & Legal:

Ex: Tata Consultancy Services preserved 50 million historical legal documents on piqlFilm on behalf of the High Court of Madya Pradesh in India.


Bank & Insurance:

Many banks still have a vast amount of paper records they are obliged to archive both for legal and business reasons. Ex. one of Piql’s clients used to spend EUR 250 000 monthly on physically storing their paper archive at a remote location. By writing the documents on piqlFilm, the efficiency, cost-effectiveness, and security has improved immensely.
