Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article introduces a novel visual cryptography method based on ghost imaging and Hadamard transform, addressing the limitations of traditional visual cryptography. By dividing a secret image into two visual key images and utilizing ghost imaging techniques, the method allows for high-security encryption and decryption processes. The use of Hadamard patterns ensures efficient and effective reconstruction of the secret image, making this method suitable for various applications such as data hiding, key management, and digital watermarking. The article also discusses the robustness and security of the method, highlighting its potential for practical applications in identity authentication and digital watermarking. Simulations and experiments validate the feasibility and effectiveness of the proposed method, demonstrating its potential to expand the application scope of visual cryptography.
