Hi Nidhi Soni! The query that you have arisen is a major problem nowadays. But, I have a suggestion for you.
If you are using an Android device, I would recommend you an app named "Logext: Add Logo Watermark and Text Sign to Photos". You can download this application from Google Play Store.
This application provides Copyright stamps, Trademark Stamps, Rubber stamp and many more. You can also add Add logo of your business on the photo.
In short, it will safeguard your business Logo with this app.
Hope, this works for you!
