How viable isDigital Rights Management

IntroductionDigital Right Management:Commonly known as DRM.The term is used to describe any technology which makes the unauthorized use of digital content.Sony, Apple Inc., Microsoft and the BBC use DRM technology.2Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

Commonly known as DRM.

The term is used to describe any technology which makes the unauthorized use of digital content.

Sony, Apple Inc., Microsoft and the BBC use DRM technology.

OverviewMost current DRM schema are based on the notation that the user is untrustworthy and the use of protected content must be restricted.This gives rise the interoperability issue among DRM schema.So to built a trusted infrastructure to protect the content is being difficult.The computer community revisit the current approaches.3Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

Most current DRM schema are based on the notation that the user is untrustworthy and the use of protected content must be restricted.

This gives rise the interoperability issue among DRM schema.

So to built a trusted infrastructure to protect the content is being difficult.

The computer community revisit the current approaches.

A framework makes the DRM schema transparent.

User can consume protected content with the list amount of information loss.

Why Interoperability is ComplexInteroperability works with trusted modelPKI(Public Key Infrastructure) is an example of trust model.For Example:OMA(Open Mobile Alliances) use PKIMPEG-21 DRM schema does not specify a particular authentication framework.These differences makes complexity. 10Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

Interoperability works with trusted model

PKI(Public Key Infrastructure) is an example of trust model.

For Example:

OMA(Open Mobile Alliances) use PKI

MPEG-21 DRM schema does not specify a particular authentication framework.

These differences makes complexity.

Open problemsTo achieve inner-DRM the computing community must meet two major challenges:Preserving the protection levelBuilding a trusted environment.11Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

To achieve inner-DRM the computing community must meet two major challenges:

Preserving the protection level

Building a trusted environment.

Conclusion Much work remain to bring DRM technology in line with customer and business demand.A strong platform should make at the business level to protect unauthorized data passingThe new technology should enough friendly for the user.12Qudrat-E-Alahy Ratul, Kuet, Khulna, Bangladesh

Much work remain to bring DRM technology in line with customer and business demand.

A strong platform should make at the business level to protect unauthorized data passing

The new technology should enough friendly for the user.
