According to cybersecurity reports, 1 in 3 "keygen" or "crack" files for graphics software contains a Remote Access Trojan (RAT) or cryptocurrency miner. PSD codecs are particularly vulnerable because they operate at the kernel level (inside Windows Explorer), giving them deep system access.
| NFR | Target |
|-----|--------|
| Performance | Reading/writing the block must add ≤ 2 ms per file (measured on SSD, 2 GB PSD). |
| Scalability | Search index must handle ≥ 10 M assets with < 200 ms latency for serial‑number look‑ups. |
| Security | Values are not considered PII, but must be stored encrypted at rest if the asset is marked sensitive. |
| Compatibility | The custom block must not break Photoshop ≥ 2020, GIMP, or any other PSD‑compatible viewer (they will simply ignore unknown block). |
| Reliability | Corrupted or missing block → fallback to “unknown” and log a warning; do not abort the load. |
| Internationalization | serialName may contain Unicode characters (e.g., Japanese project names). Store as UTF‑8; UI fields must support full Unicode. |
| Auditability | All updates to the fields are logged with user ID, timestamp, and previous value (audit table asset_serial_log). | psd codec serial number name
