DefinitionsAccess restriction on Satellite TVAccess restriction on NextShareProposed solution

Introduction

DefinitionsI Restrict distribution

I Do not allow downloadingI Restrict access

I Allow downloadingI Do not allow consumption



Conclusions


Introduction

Access restriction on Satellite TV



Conclusions


Introduction

Access restriction on NextShareI Required by content ownersI Technical requirements on NextShare:

I Efficient distributionI Caching



Conclusions


Introduction

Proposed solution

I Access Control outside the coreI Distribution mechanism untouchedI Caching support

I BenefitsI Easy to support different ACSsI Should ACS be compromised

I Core system unaffectedI Can easily be replaced

I Develop a framework



Conclusions

Access Control Integrationon NextShare

I Develop an AccessControl Framework



Conclusions




I Implement sample ACSsI Password



Conclusions




I Implement samble ACSsI PasswordI sACS



Conclusions



Example 1: protection by password

Conclusions



Example 2: simple Access Control System (sACS)Supports

I GeoIPI IpRangeI Other Access token mechanism

I Payment system



Conclusions


Remember: Access restriction on Satellite TV



Conclusions


Exactly the same protection model as Satellite TV!

Conclusions



sACS: Real demonstration!!I The prototype is already prepared to be shownI If you are interested, ask me for it!

I I will be around today and tomorrow
