We present a\n\t\t\t\t\tsynthetic-aperture-constrained dual-layer watermarking framework for\n\t\t\t\t\tpost-acquisition FPM release. A robust layer carries a 256-bit\n\t\t\t\t\tauthenticated provenance record through reliability-guided\n\t\t\t\t\tdifferential quantization index modulation of recoverable Fourier\n\t\t\t\t\tcoefficient pairs, while a semi-fragile layer tests raw-stack\n\t\t\t\t\tconsistency. Across six simulated acquisition conditions, the mean\n\t\t\t\t\trobust bit-error rate (BER) is 1.47%, whereas 1000 independent\n\t\t\t\t\twrong keys yield 0.4998\u00b10.0316 BER. A generic Fourier-QIM\n\t\t\t\t\tbaseline exhibits a substantially larger BER, and representative\n\t\t\t\t\traw-stack processing tests distinguish persistent provenance recovery\n\t\t\t\t\tfrom semi-fragile consistency rejection. A real blood-smear spectrum\n\t\t\t\t\tretains zero correct-key BER after model-consistent FPM release and\n\t\t\t\t\tsequential ePIE reconstruction, with amplitude SSIM 0.9971.<\/jats:p>","DOI":"10.1364\/ol.609347","type":"journal-article","created":{"date-parts":[[2026,8,16]],"date-time":"2026-08-16T18:00:10Z","timestamp":1786903210000},"page":"5213","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dual-layer watermarking for secure Fourier ptychographic\n\t\t\t\tmicroscopy"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-4153-0470","authenticated-orcid":true,"given":"Jiurun","family":"Chen","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03cve4549","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Network Intelligence Research Department"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanqi","family":"Chen","sequence":"additional","affiliation":[{"name":"University of Chinese Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Xu","sequence":"additional","affiliation":[{"name":"Shenzhen Children\u2019s Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Huang","sequence":"additional","affiliation":[{"name":"Network Intelligence Research Department"},{"name":"Shenzhen Shengqiang Technology Co."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Song","sequence":"additional","affiliation":[{"name":"Network Intelligence Research Department"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonghong","family":"He","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03cve4549","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Research Institute of Tsinghua"},{"name":"Jinfeng Laboratory"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"ol-51-18-5213-R1","doi-asserted-by":"publisher","first-page":"739","DOI":"10.1038\/nphoton.2013.187","type":"journal-article","volume":"7","author":"Zheng","year":"2013","journal-title":"Nat.
