Real-world Use Cases

Sentra is deployed across various industries, creating tailored solutions through custom AI models, RAG pipelines, and Verifiable Credentials.

Enterprise & IT Construction​

The Challenge: Severe knowledge loss due to employee turnover and buried Chatwork/Slack histories. Onboarding new engineers took weeks.

The Sentra Solution:

  • Data Ingestion: Sentra imported years of historical Chatwork and Slack data into a vectorized Knowledge Base.
  • Instant Access: Deployed the Sentra Slack bot.
  • The Result: When new hires ask technical setup questions in Slack, Sentra instantly retrieves the historical context and provides the answer. Organizational knowledge loss dropped to zero, and onboarding time was drastically reduced.

Medical & Healthcare​

The Challenge: A specialized women's clinic needed to scale the head physician's localized expertise to both patients (24/7) and staff (for training) without increasing the physician's workload.

The Sentra Solution:

  • Knowledge Base: Ingested the physician's published books, clinical policies, and seminar audio transcripts.
  • Role-Based Access (RBAC):
    • Patients: Interact with a public-facing LINE bot restricted to general Q&A.
    • Nurses: Access internal operational manuals and treatment protocols.
    • Doctors: Full access to high-level clinical policy decisions.
  • The Result: 24/7 consistent patient care and a unified, role-segregated training platform for staff.

Special Needs Education & Care​

The Challenge: Therapists were spending 1-2 hours after every session manually transcribing notes and generating Excel-based support plans.

The Sentra Solution:

  • Audio-to-Document Workflow: Therapists simply upload the session audio recording to Sentra.
  • Automated Pipeline: Sentra runs speech-to-text, extracts key therapeutic milestones, and automatically generates the formatted Excel Support Plan.
  • The Result: Documentation time dropped from hours to minutes, allowing therapists to focus entirely on patient care.

Custom Deployments: Government Patent Registry​

The Challenge: A government entity needed a highly secure, non-LLM based method to find semantic similarities between millions of highly technical patent filings.

The Sentra Solution:

  • Custom AI Development: Utilizing Bitgrit's network of data scientists, a custom Similarity Search model was developed.
  • TEE Processing: Data is processed within a Trusted Execution Environment to guarantee the confidentiality of unreleased patent data.
  • The Result: Fast, highly accurate similarity matching without exposing sensitive IP to public generative models.

Identity: Academic Credentials (Student Pass & Graduation Cert)​

The Challenge: Universities face rampant diploma fraud and lack an efficient way to verify current student enrollment for campus services or alumni status for employers.

The Sentra Solution:

  • Alpha Credentials: The university issues electronic Student Passes and Graduation Certificates as W3C Verifiable Credentials directly to the Sentra Wallet.
  • The Result: Employers can instantly cryptographically verify a graduation certificate. Students can present their Student Pass for campus access or student discounts without revealing their full identity profile.

Identity: Electronic Vouchers & Coupons​

The Challenge: Retail chains struggle with coupon fraud and tracking the lifecycle of high-value electronic vouchers without enforcing cumbersome user registration.

The Sentra Solution:

  • Common Attribute Credentials (CAC): A single-attribute "Voucher" VC is issued to the user's Sentra Wallet.
  • The Result: Upon redemption, the point-of-sale system requests proof of the voucher. The Sentra DID registry guarantees the voucher is authentic, valid, and automatically flags it in the Revocation Registry once used, preventing double-spending.

Identity: Municipal & Prefecture Residency (Pref)​

The Challenge: Local governments require secure proof of residency to distribute local benefits, but centralized citizen databases pose massive honeypot security risks.

The Sentra Solution:

  • Decentralized Proofs: Municipalities issue a "Prefecture" Verifiable Credential.
  • The Result: Citizens use this credential via Sentra ID to instantly authenticate their residency for municipal web services, ensuring they receive benefits while keeping their personal data fully isolated and localized to their own device.
