Information rights management

Information rights management is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Information rights management rather than just read about it. In short: Information rights management (IRM) is a subset of digital rights management (DRM), technologies that protect sensitive information from unauthorized access. It is sometimes referred to as E-DRM or Enterprise Digital Rights Management.

Key takeaways

Information rights management belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Information rights management to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Information rights management from memory before moving on to harder problems.

Reference excerpt

Information rights management (IRM) is a subset of digital rights management (DRM), technologies that protect sensitive information from unauthorized access. It is sometimes referred to as E-DRM or Enterprise Digital Rights Management. This can cause confusion, because digital rights management (DRM) technologies are typically associated with business-to-consumer systems designed to protect rich media such as music and video. IRM is a technology which allows for information (mostly in the form of documents) to be ‘remote controlled’. This means that information and its control can now be separately created, viewed, edited and distributed. A true IRM system is typically used to protect information in a business-to-business model, such as financial data, intellectual property and executive communications. IRM currently applies mainly to documents and emails.

Features IRM technologies typically have a number of features that allow an owner to control, manage and secure information from unwanted access.

Information encryption Information rights management solutions use encryption to prevent unauthorized access. A key or password can be used to control access to the encrypted data.

Permissions management Once a document is encrypted against unauthorized users, an IRM user can apply certain access permissions that permit or deny a user from taking certain actions on a piece of information. Some of these standard permissions are included below.

Strong in use protection, such as controlling copy & paste, preventing screenshots, printing, editing. A rights model/policy which allows for easy mapping of business classifications to information. Offline use allowing for users to create/access IRM sealed documents without needing network access for certain periods of time. Full auditing of both access to documents as well as changes to the rights/policy by business users. It also allows users to change or revoke access permissions without sharing the document again.

Examples An example of IRM in use would be to secure a sensitive engineering document being distributed in an environment where the document's recipients could not necessarily be trusted. Alternatively, an e-mail could be secured with IRM. If an email is accidentally forwarded to an untrusted party, only authorized users can gain access. A well designed IRM system will not limit the ability for information to be shared. Rules are enforced only when people attempt to gain access. This is important as often people share sensitive information with users who should legitimately have access but don't. Technology must facilitate control over sensitive information in such a situation. IRM is far more secure than shared secret passwords. Key management is used to protect the information whilst it is at rest on a hard disk, network drive or other storage device. IRM continues to protect and control access to the document when it is in use. Functionality such as preventing screen shots, disallowing the copying of data from the secure document to an insecure environment and guarding the information from programmatic attack, are key elements of an effective IRM solution.

Naming conventions Information rights management is also known by the following names:

Worked examples

Example 1 — a first encounter with Information rights management

Start with the simplest possible case. Write down what Information rights management claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Information rights management before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Information rights management ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Information rights management

In research: Information rights management appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Information rights management in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Information rights management is common in secondary-school and first-year university syllabi. It links to neighbouring topics Digital rights management, so understanding it makes those chapters shorter.
In everyday life: Look for Information rights management outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Information rights management in simple terms?

Why does Information rights management matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Information rights management?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
