CBSE Refutes Claims: OSM Portal Remains Secure

CBSE denies OSM portal breach, clarifies testing site usage and security measures. Get the full details here.

Amid a swirl of social‑media rumours, the Central Board of Secondary Education (CBSE) has issued a firm clarification that the OSM portal used for evaluating answer scripts is not compromised. The board’s statement directly addresses the viral post that claimed a breach of a website linked to the system, assuring students, parents and schools that their examination data remains safe.

The post in question pointed to the URL http://cbse.onmarks.co.in and alleged that it had been breached, exposing real marks and personal details. CBSE responded that this particular link is merely a testing platform, employed internally for sample data and review purposes. No genuine examination data, marks or student records are stored on that site, the board said.

Crucially, the board highlighted that the actual evaluation portal—where answer books are uploaded, marked and scores are generated—operates on a completely separate system. According to CBSE, this operational platform has not shown any sign of a security breach, and its integrity remains intact.

CBSE further explained that the On Screen Marking (OSM) system was introduced to bring greater transparency to the assessment process. The digital framework includes built‑in grievance redressal mechanisms, allowing candidates to raise concerns directly through the portal. Strong safeguards, such as encryption and access controls, have been embedded to maintain data integrity and security throughout the marking cycle.

The clarification came after a Class 12 Physics student named Vedant posted on X (formerly Twitter) that his answer script displayed handwriting that did not match his own. The post quickly went viral, sparking anxiety among thousands of students awaiting their results. While the board acknowledged the heightened emotions, it reiterated that the OSM portal itself has not been tampered with.

Several other students have reportedly raised similar concerns, alleging mismatched answer sheets or marking inconsistencies after the recent Class 12 board results. CBSE has urged these students to use the official grievance channels rather than relying on unverified social‑media claims. The board assured that any genuine technical glitches are being investigated and resolved promptly.

In addition to the security assurances, CBSE reminded stakeholders that the OSM portal was rolled out to streamline the marking process and reduce human errors associated with manual evaluation. By digitising the marking workflow, the board aims to deliver results faster and with greater accuracy.

The board also highlighted that the OSM platform’s design incorporates multiple layers of verification. Markers are assigned unique credentials, and each step of the marking – from scanning answer sheets to assigning marks – is logged for audit purposes. These logs help the board trace any irregularities and act swiftly if any discrepancy arises.

Despite the board’s reassurance, the episode underscores a broader challenge: the rapid spread of misinformation on digital platforms. CBSE urged the public to verify information from official sources before sharing or reacting to claims that could cause unwarranted panic.

For students seeking clarification on their answer sheets, CBSE has extended the deadline for answer sheet requests. The new cut‑off allows candidates to apply until May 23, giving them ample time to raise any genuine concerns through the proper channels.

Meanwhile, the board has also taken steps to improve the portal’s user experience. Recent updates aim to fix payment failures reported by some users during the re‑evaluation fee process, and to resolve issues of blurred answer sheet images that earlier caused confusion.

CBSE’s clarification puts to rest the rumors of a compromised OSM portal, reaffirming that the live evaluation system is secure and equipped with strong safeguards. Students are encouraged to follow official procedures for any genuine grievances.
