I'm developing an application which will be storing user sensitive data. My issue is using other applications that a user can view that stored data with. Then I need to provide better security for the data in general.
Is there any way to provide better security for SQLite database and tables?
The author of sqlite offers a version that encrypts data. It's not free though
Encrypt your data before you enter it in the database. As far as I know, the SQLite database is kept in a single file somewhere in the /data/ directory. What is more, your data is kept in plain text format. This means that it will always be possible for someone to extract that data by rooting the phone, obtaining the .db SQLite file and opening it with a text editor.
So, encrypt your data :)
-- Okay, maybe not a text editor, but a simple hex editor. Anyways...
Check out SQLCipher for Android. It's free (Apache 2 and BSD licences).
PS.: Some ORMs also support SQLCipher now, e.g. our greenDAO.
You could encrypt the data using a user specific salt retrieved from your server. That way, even with root access you would need the users salt to decrypt the database. Since you have control over the salt you provide an extra layer of security, however, your user will always need a network connection to access their data.
why are you keeping sensitive data on the phone? If its sensitive, why not send it back to the server where you have control over things. If the user roots their phone, they can basically do what they want. Other than that, encrypting like Shade mentioned would probably be your only option...
Good way to protect the the Database is to use the password Protected database and you can create it by using
1- android Sql3 wrapper library
2- libsqlite3_jni.so
also please read the article below are make your search on the option above, i hope this would help much.
