Chats & groups
Available individual and group messages, replies, reactions, announcements and system events reconstructed in context.
Messaging application evidence
LINE
Forensics.
Forensic examination of LINE chats, calls, groups, shared media, historic Keep artefacts where retained, account records and associated device artefacts.

What we can
establish.
Every instruction begins with the questions to be answered. Available evidence depends on the device, software, state, credentials, backups and prior handling.
Calls & voice content
Available voice and video call artefacts, voice messages and related timestamps correlated with other device activity.
Media & historic Keep
Shared photographs, videos, files, albums, notes and historic Keep artefacts, Keep Memo material or caches where retained examined with storage traces.
Contacts & account identity
LINE IDs, profiles, contact relationships, group membership and account changes assessed for identity and attribution.
Backups & linked devices
Available chat backups, desktop artefacts and authorised linked-device records considered where technically accessible.
Deletion & authenticity
Deleted content and claimed conversations tested against databases, media, notifications, backups and counterpart evidence.
Evidence source map
Beyond the
visible application.
Absence from one screen or device does not resolve the evidential question. Relevant records may be distributed across several sources.
Local records
Accessible chats, calls, attachments, group records and historic Keep artefacts where retained.
Backup and account
Configured chat backups or exports require platform, account and backup-setting checks.
Existing linked endpoints
Existing desktop records may be incomplete or have different retention.
Limits and corroboration
LINE Keep ended on 28 August 2024. Keep Memo is a separate feature; no live Keep archive is promised. Lawfully obtained counterpart records may corroborate the source.
Evidential perspective
Account migration and backup history matter.
LINE evidence can be affected by device changes, account transfers, backup settings and regional application versions. Those factors are established before absence of data is interpreted as absence of communication.
Preserve now
Protect the
best evidence.
- 01Do not reset, update, reinstall or casually browse the application.
- 02Record the device, lock, power and network state.
- 03Identify backups, linked computers and counterpart devices promptly.
- 04Secure known credentials separately and maintain custody records.
Typical deliverables
Acquisition record
Device details, condition, method, tool, integrity information and material acquisition limitations.
Evidence schedule
Relevant conversations, attachments, timestamps, identifiers and supporting artefacts in a reviewable form.
Findings report
Plain-English findings with source references, alternative explanations and express evidential limitations.
Our approach
Proportionate.
Documented.
Explainable.
- 01Authority, objectives and device state confirmed.
- 02Acquisition method selected to preserve the best available evidence.
- 03Findings correlated and tested against alternative explanations.
- 04Clear reporting of methodology, findings and limitations.
Sources and interpretation
Each entry identifies its limited supporting proposition and documentation-check date. General methodology is not a current device-support list. These checks are not laboratory validation; availability and method suitability require assessment for the exact source and configuration.
