An LTI 1.3 Plagiarism Checker is an academic integrity tool built on the 1EdTech LTI Advantage open standard—utilizing OAuth 2.0 and OpenID Connect encryption to integrate natively into Learning Management Systems like Canvas, Blackboard, Schoology, and Brightspace with automated roster synchronization, embedded SpeedGrader reports, and two-way grade passback.
For years, educational technology relied on legacy LTI 1.1 connections, which used basic shared secret keys that were vulnerable to security breaches and offered limited functionality. Modern educational institutions now mandate LTI 1.3 (LTI Advantage) as the gold standard for software procurement. An LTI 1.3 plagiarism checker like Checkmark Plagiarism operates directly inside your LMS interface, eliminating external logins, protecting student data privacy under FERPA, and automating the entire grading workflow.
Below is a comprehensive technical and pedagogical guide on what LTI 1.3 means for schools, IT administrators, and classroom educators.
Checkmark Plagiarism is a certified LTI 1.3 platform pairing plagiarism detection with essay writing playback, AI detection, autograding, and native Canvas LMS integration.
The 4 Core Services of LTI 1.3 (LTI Advantage)
1. OAuth 2.0 & OpenID Connect Security
Replaces static shared secrets with dynamic, encrypted asymmetric JSON Web Tokens (JWT), ensuring bank-grade security and full FERPA compliance.
2. Assignment and Grade Services (AGS)
Enables automated, real-time two-way synchronization of numeric grades, letter marks, and granular rubric ratings directly into the LMS Gradebook.
3. Names and Role Provisioning Services (NRPS)
Automatically synchronizes course rosters and permissions—distinguishing between instructors, co-teachers, and students without manual account creation.
4. Deep Linking & Embedded SpeedGrader Views
Allows teachers to configure Checkmark directly within assignment settings and view complete similarity reports directly inside Canvas SpeedGrader.
Why School IT Administrators Mandate LTI 1.3
For district technology directors and university IT coordinators, LTI 1.3 compliance is non-negotiable:
- Elimination of Data Leakage: Legacy LTI 1.1 transmitted data via unencrypted URL parameters. LTI 1.3 ensures all student payloads are signed and encrypted end-to-end.
- Single Sign-On (SSO): Teachers and students never have to remember separate passwords; authentication occurs instantly through their existing LMS credentials.
- Zero Maintenance Overhead: Roster changes, student enrollments, and course additions sync automatically without manual IT CSV uploads.
