Sourabh Sharma, Harish Sharma, Janki Ballabh Sharma

Abstract: Highlights•Image adaptive watermarking using dynamic embedding strength factor optimized by ABC.•Improving embedding capacity using redundant discrete wavelet transform.•Embedding in principal component to remove the problem of false positive error.•Arnold chaotic map is used to provide extra security.•Proposed algorithm can resist multiple attacks and extract the correct watermark.
