Check the Audience Before Sharing

A link's permissions determine who can use it.

Institute lesson · Published October 19, 2026

The concept

Sharing is an access decision. A document link may be restricted to named people, available to an organization, or open to anyone who obtains it. The wording of the message does not enforce the intended audience. Check the actual permission setting, the necessity of editing access, and how long access should remain available.

Worked example

A fictional neighborhood committee shares a survey analysis with an outside printer. The document also contains a hidden worksheet of residents' responses. Rather than sending the editable master file, the coordinator creates a clean publication copy with only the approved results, verifies its contents, and grants the printer the minimum access needed. After printing, the coordinator removes access according to the agreed process.

Limits and judgment

Removing access later does not retrieve copies already downloaded or photographed. Hidden tabs, comments, revision history, and metadata may contain information absent from the visible page. The appropriate review depends on the file type and purpose. For recurring public releases, a standard preparation and checking procedure is more reliable than remembering each possible disclosure risk under deadline pressure.

FROM UNDERSTANDING TO ACTION

Put it to work.

Write a pre-sharing checklist for a public report containing survey results.

RETRIEVE. REASON. REMEMBER.

Knowledge check.

Choose one answer for each question, then check your reasoning.

1. What enforces a link's audience?
2. What can revoked access fail to recover?
