Streaming and media application security is judged by what sits outside the DRM. Your DRM system protects the encrypted video path. Otukan protects everything around it: the code that decides who may watch, the requests that fetch licences, offline downloads and cached assets, ad logic and the screens DRM does not reach. It detects modded clients that unlock paid tiers or remove ads, exposes scripted access to sign-in and catalogue APIs, and sends evidence to your entitlement and licence services. Every control carries a separate scope for Android and for iOS.
Media flows and their trust boundaries
A streaming app makes many small trust decisions every session. Each one is a boundary where something on the phone asks a service to hand over value.
| Flow | Trust boundary | What goes wrong | Otukan control |
|---|---|---|---|
| Sign-in and profiles | Identity service | Leaked passwords tested at scale, resold accounts | Attestation, automation signals |
| Entitlement checks | Subscription service | Patched client claims a premium tier | Integrity checks, app shielding |
| Licence and manifest requests | Licence service | Tools outside the app request playback directly | Attestation on protected requests |
| Offline downloads | Device storage | Downloads copied from a rooted or jailbroken phone | Data loss prevention, runtime checks |
| Ad-supported tiers | Ad decisioning | Mods that skip or strip ads | Anti-tampering, integrity checks |
| Previews, articles, chat | App screens | Capture of content DRM does not cover | Screen capture protection |
Ad-supported tiers deserve particular attention. A mod that removes ads costs you the impression and the advertiser’s confidence in your audience figures, and it spreads quickly through unofficial download sites. The most expensive failures happen at entitlement and licence requests, because a modded client that passes them unlocks the whole catalogue for everyone who installs it.

App, operating system and backend responsibilities
The app, with Otukan
Otukan hardens your app’s code with obfuscation, checks its integrity while it runs, and detects hooking, debugging, root and jailbreak. It protects content the app stores on the device and shields screens that DRM does not reach. It then attaches its findings to the requests your services care about.
The operating system and your DRM
Android and iOS provide the secure video path, hardware-backed keys where available, and attestation through Play Integrity and App Attest. On Android, an app can mark a screen secure so screenshots and recordings of it are blocked. On iOS, apps cannot block screenshots but can detect recording and mirroring. Your DRM system uses the platform’s protected playback path. Otukan works beside it, not inside it. The division is deliberate: your DRM keeps doing what it was chosen for, and Otukan adds a trustworthy client in front of it.
Your backend
Your entitlement, licence and sign-in services verify Otukan’s evidence and make the call: stream, download, challenge or refuse. Concurrency limits and household rules stay there too. For how downloaded and cached content is protected, see data loss prevention.
Evaluating protection for a media app
Supported platforms
Ask for scope per control and per platform. Screen capture works differently on Android and iOS, and download protection depends on each platform’s storage model. Otukan states Android and iOS scope separately and covers apps built with Flutter and React Native. Television and set-top apps are scoped per enquiry.
Evidence your platform can act on
Signals only matter if a service reads them. Otukan agrees with your team which field each service checks, what a failed check means, and how results are logged for anti-piracy and account security teams.
Viewer impact
Viewers judge an app by how fast playback starts. Otukan tests protected builds for start-up time, playback start and download behaviour on the phones and tablets your audience uses. New signals start in observe mode, and responses target premium playback and downloads rather than browsing or free content. Policy changes reach viewers without waiting for a store release, so tuning can follow a major live event or a new season.
Scripted catalogue scraping and login testing are covered on mobile bot detection. The complete Otukan application product is presented on mobile app security. Media apps already in the stores qualify for a free App Exposure Check of the public version.
