Digitalising Historic Police Archives: From Paper to Searchable Records

Many police zones hold decades of paper incident reports, complaint files and administrative records in basement storage or off-site depots. Retrieving a document for a cold case or a court request can take weeks. At the same time, storage costs rise, the risk of loss from flooding or relocation grows, and files can become untraceable precisely when they are needed most.

Digitising a historic police archive is not simply a scanning exercise. It requires a structured approach that respects legal retention obligations, maintains traceability for every document, and produces a tamper-proof digital archive as the end result.

A well-planned digitisation project follows four consecutive steps.

Inventory and retention planning: Which files are subject to which statutory retention period? A thorough inventory determines what must be scanned, what can be destroyed, and what must remain in physical storage.

Batch scanning with barcode tracking: Boxes and files receive barcode labels before scanning begins. Every document is traceable at every stage, from depot to digital archive. ScanFactory handles production scanning, either on-site or off-site.

OCR and metadata indexing: Every scanned document receives full-text OCR and structured metadata: date, document type, case number. Full-text search becomes possible even for documents from the 1980s and 1990s.

Ingestion into the tamper-proof archive: Digitised documents are loaded into iGuana iDM (iStore), a WORM-compliant digital archive. Every document is stored immutably with a complete audit log.

For police records, traceability is not optional. Every movement of a box or file is recorded, from the initial inventory through transport to final storage in iGuana iDM. The audit log captures who scanned, indexed or consulted each document and when. This is not only relevant internally; it is also required during judicial checks or inspections by supervisory authorities.

Once the statutory retention period expires, paper originals can be destroyed in a compliant manner. Certified destruction closes the loop: the paper is removed in a demonstrable, GDPR-compliant way, while the digital archive is retained for as long as the retention schedule requires.

Full-text OCR makes a tangible difference for operational retrieval. An investigator who enters a name or case number sees all relevant documents within seconds, regardless of whether they date from 1995 or 2015. Limitation-period reviews, cold cases and court requests become manageable without staff having to search through physical boxes.

Police zones covered by Belgian public procurement frameworks may be able to use existing framework agreements for archive digitisation, avoiding a separate tendering procedure. Ask your procurement team to confirm which lot applies.
